SteelSeries Rival 600 vs. Glorious Model O for Competitive Play
The SteelSeries Rival 600 and Glorious Model O approach wired gaming mice from very different directions. Both use accurate optical sensors, configurable buttons, RGB lighting, and flexible USB cables, yet they feel almost unrelated in the hand. The Rival 600 is a substantial right-handed mouse with adjustable weight, while the Model O is an extremely light shell designed to disappear beneath fast, sweeping movements.
That difference matters more than a specification sheet suggests. Sensor resolution and polling rate are already sufficient on both mice for competitive games, so shape, weight distribution, grip style, and cable behavior have a greater effect on daily use. A player who enjoys a palm-filling ergonomic design may find the Model O too flat, while someone accustomed to lightweight esports mice may consider the Rival 600 heavy and slow.
The age of each design also affects the buying decision. SteelSeries built the Rival 600 around customization and tracking consistency, whereas Glorious focused on reducing mass and creating an open honeycomb chassis. Neither is universally better. The right choice depends on whether controlled support or effortless speed is the priority.
Shape And Hand Position
The Rival 600 has a pronounced right-handed ergonomic profile. Its left side rises into a palm hump, and its right edge provides a stable shelf for the ring and little fingers. The design supports a fuller grip, especially for palm and relaxed claw users. The thumb rests beside two side buttons that are easy to reach without shifting the hand.
The Model O uses a symmetrical shell with a flatter, lower body. Its dimensions make it suitable for right-handed users, although left-handed players can physically use the shape if the side buttons are not a concern. The rear is rounded without the pronounced palm support found on the Rival 600, encouraging fingertip and claw grips. A palm grip remains possible for medium-sized hands, but the low height gives less contact and leverage.
Hand size changes the result considerably. Large hands may appreciate the Rival 600’s broad body and extended length, while smaller hands can struggle to reach its thumb buttons or control its taller rear. The Model O is easier to move with the fingertips and often feels less restrictive, though its width and low profile may leave some users wanting more support under the palm.
Weight And Movement
Weight is the clearest dividing line. The standard Glorious Model O weighs roughly 67 grams, depending on finish and production version. Its perforated shell removes material across the top and sides, creating a mouse that responds quickly to small changes in direction. In fast shooters, that low mass reduces the effort needed for rapid turns, recoil control, and repeated target transitions.
The Rival 600 starts at approximately 96 grams and can reach about 128 grams with its included side weights. That makes it a heavy mouse by current competitive standards, even before customization. The weight system is useful for users who prefer a grounded, deliberate feel, but it cannot transform the Rival 600 into an ultralight. Its balance remains focused on control and stability rather than effortless acceleration.
The extra mass can be beneficial outside twitch-focused shooters. Strategy games, role-playing games, productivity, and slower tactical titles may feel comfortable with the Rival 600’s planted movement. The Model O has the advantage for low-sensitivity aim and large mouse-pad sweeps, where every gram becomes noticeable over a long session.
Sensors, Buttons, And Software
SteelSeries equipped the Rival 600 with the TrueMove3 optical sensor and a dedicated lift-off distance sensor. The primary sensor offers up to 12,000 CPI, while the second sensor measures when the mouse leaves the surface. This allows the mouse to stop tracking at a highly controlled height, which helps players who frequently lift and reposition their mouse during low-sensitivity play.
The Model O uses the PixArt PMW3360, a proven 12,000 DPI-class optical sensor with excellent tracking accuracy. In practical gaming, both mice provide dependable performance at sensible sensitivity settings. Differences in aim consistency are more likely to come from shape, weight, feet, grip tension, and surface choice than from the maximum CPI number.
The Rival 600 provides seven programmable buttons, including two main clicks, a clickable scroll wheel, two side buttons, and a pair of buttons behind the wheel. These extra controls are useful for ability-heavy games, push-to-talk, media controls, or productivity shortcuts. The Model O has six buttons and a simpler layout, with two side buttons that suit common game bindings without crowding the shell.
SteelSeries GG handles profiles, button assignments, CPI settings, lift-off adjustment, and RGB effects for the Rival 600. Glorious software provides similar control for the Model O, though the exact application and firmware support can vary between original and later Model O revisions. Both mice allow onboard settings for essential functions, but software installation may be needed for deeper customization.

Cable, Feet, And Build Quality
The Model O’s flexible “Ascended” style cable is one of its strongest features. It produces less drag than a stiff rubber lead and can feel close to wireless during fast movements when routed through a mouse bungee. Its PTFE feet also contribute to a quick glide, especially on a smooth cloth or hybrid mouse pad. The combination of low weight, slick feet, and a compliant cable defines the Model O’s character.
The Rival 600 uses a braided cable that feels durable, though it is generally firmer and more noticeable on the desk. A bungee helps keep the cable elevated and prevents it from catching against the edge of a pad. The mouse feet glide well when clean and undamaged, but the Rival 600’s higher mass makes the same surface feel slower than it does with the Model O.
Both designs use plastic construction, with different compromises. The Model O’s perforations reduce weight and allow more airflow, but they expose the interior to dust, crumbs, and moisture. Users with sweaty hands may also notice that the open shell changes the way the mouse feels during long sessions. The Rival 600’s closed body is easier to wipe down and offers more protection from debris.
The Rival 600’s removable side grips and modular weight compartment add practical flexibility, but they also introduce more parts and seams. Long-term reliability depends on switch condition, cable strain, scroll-wheel wear, and general maintenance. A honeycomb mouse should be cleaned carefully with compressed air and a soft brush rather than exposed to liquid.
Gaming Performance And Comfort
In competitive first-person shooters, the Model O has the immediate advantage in speed. Flicks require less force, and repeated lifts are less tiring when the mouse weighs around two-thirds as much as the Rival 600. Its broad, low shell can also provide enough lateral support for claw grip without forcing the wrist into a steep angle.
The Rival 600 feels more controlled when the hand benefits from a defined anchor point. Its palm hump fills the rear of the hand, and the side contours reduce the need to pinch the mouse with the thumb and little finger. This can make long sessions comfortable for users who dislike flat esports shapes. The trade-off is greater inertia, particularly when changing direction quickly.
The additional buttons on the Rival 600 help in games with frequent commands. Massively multiplayer online games, multiplayer battle arenas, and simulation titles can benefit from the extra inputs without requiring a separate keypad. For competitive shooters, the Model O’s simpler layout may be preferable because it reduces accidental presses and keeps the shell uncluttered.
Comfort is highly personal, but grip style offers a useful starting point. Palm users typically receive more support from the Rival 600, while fingertip players usually gain more freedom from the Model O. Claw grip can work well on both: the Rival 600 gives a fuller rear contact point, and the Model O offers a lighter, more mobile feel.
Which Mouse Fits Your Setup
Desk space and sensitivity should influence the choice. A low-sensitivity player using a large mouse pad will likely notice the Model O’s lower resistance immediately. It is easier to lift, reposition, and swing across a wide surface. A high-sensitivity player who makes short, precise movements may value the Rival 600’s steadiness more than its additional mass.
The surrounding setup also matters. A mouse bungee can improve either device, but it is especially helpful with the Rival 600’s firmer cable. A hard mouse pad can make the Model O feel extremely fast, while a control-oriented cloth surface can balance its quick feet. The Rival 600 may feel more natural on a smooth cloth pad that provides a small amount of braking.
RGB lighting is more visible on the Model O because light passes through its honeycomb shell and internal diffuser. The Rival 600 uses multiple illumination zones around the shell and wheel, producing a more conventional gaming aesthetic. Lighting has no performance benefit, but it can matter for matching a wider PC setup.
Pricing and availability may ultimately decide the purchase. The Rival 600 is an older model and is often found through discounted stock, while the Model O has had several revisions and surface options over time. Checking the exact version, included accessories, warranty coverage, and replacement feet is worthwhile when comparing listings from different retailers.
Recommendations For Different Players
- Choose the Glorious Model O if low weight, rapid repositioning, and fingertip or claw grip are your main priorities.
- Choose the SteelSeries Rival 600 if you prefer a supportive right-handed shape, extra buttons, and a stable palm-centered feel.
- Favor the Model O for competitive shooters played at low sensitivity across a large mouse pad.
- Favor the Rival 600 for mixed gaming, productivity, MMO keybinds, or users who find flat lightweight mice uncomfortable.
- Consider a different modern ultralight ergonomic mouse if you want the Rival 600’s shape without accepting its heavier chassis.
The Glorious Model O is the more convincing choice for players specifically seeking a lightweight wired gaming mouse. Its low mass, flexible cable, responsive feet, and flat symmetrical shell make fast movement feel natural. The SteelSeries Rival 600 remains attractive for a different audience: users who want a shaped, feature-rich mouse with a secure palm rest, adjustable balance, and a wider button layout.
Treat the two designs as alternatives based on hand position rather than competing sensor specifications. The Rival 600 delivers comfort and control through structure and mass; the Model O delivers speed through simplicity and aggressive weight reduction. Check your preferred grip, hand dimensions, sensitivity, and desk surface before buying, then choose the mouse that supports the way you actually play.
