Both are receiver-based competitive mice with restrained controls, but the documented shell dimensions and profiles deserve more attention than their DPI ceilings. The SUPERLIGHT 2 lists 60 g; the Viper lists 54 g for the black model. These figures do not predict individual comfort or measured aiming performance.
Shape & Size
Compare the exact dimensions in the table with a mouse you already know. Width and height do not determine comfort by themselves; the grip and hand-size research below explains the contact differences.
Weight, Sensor & Polling
The table preserves unknown fields and manufacturer reporting limits. Weight conventions, firmware and optional receivers can differ. Neither a larger DPI maximum nor a higher polling ceiling establishes lower measured latency or better aim.
Choose PRO X SUPERLIGHT 2 If…
Choose this model if you prefer a rounded symmetrical shell, five controls and USB-C charging. Current firmware supports Logitech’s documented 8K maximum, but the 95-hour battery claim does not establish 8K runtime.
Choose Viper V3 Pro If…
Choose this model if you prefer the Viper’s shell proportions and its documented 54 g black-model weight. The included high-rate receiver is a practical distinction; check the stated battery conditions when choosing a report rate.
Price Positioning
No live selling price or value winner is established here. Historical MSRP, when verified, is labelled separately in the table. Compare current new-product checkout costs, optional receivers and shipping before deciding; merchant links and commissions do not affect these conclusions.
The public RTINGS assessment supports considering several grip types with the SUPERLIGHT 2's rounded symmetrical shape. Palm support, claw contact and fingertip clearance still depend on individual hand dimensions and technique. Compare that rounded profile against the lower-feeling Viper V3 Pro and the sloped DeathAdder rather than converting a general ergonomic assessment into an exact grip rating.
Hand Size
RTINGS reports a broadly accommodating shape rather than one narrow hand-size target. Logitech's documented 125 × 63.5 × 40 mm dimensions give a useful reference against a mouse you already know. They cannot determine finger reach or palm contact on their own. Small, medium and large hand scores remain unknown because a numerical fit assessment has not been established for PeriphPick.
Gaming Use
The five-button arrangement is most straightforward for competitive FPS play with keyboard-led utility and weapon bindings. MOBA use is possible with the same division of controls. MMO suitability depends on how much of your action bar you expect to place on the mouse; a purpose-built twelve-button side panel serves a different requirement.
Connection & Battery Conditions
LIGHTSPEED requires a USB receiver; Bluetooth is not supported. The USB-C cable handles charging and data. Logitech advertises up to 95 hours of constant motion without a verified 8K-specific runtime here, so higher-rate battery planning should remain conservative. Use current G HUB and firmware when checking the supported report-rate options.
Published RTINGS commentary describes a symmetrical shape suitable for multiple grips, and distinguishes its profile from the rounder Logitech SUPERLIGHT. That supports a comparison for claw or fingertip users without establishing a universal preference. Palm users should pay attention to where the hump contacts the hand. PeriphPick has not physically evaluated the shell or measured grip comfort.
Hand Size
RTINGS's public review describes broad hand-size accommodation. The official 127.1 × 63.9 × 39.9 mm envelope helps compare overall reach with your current mouse, but grip width and contact points are not fully described by those three numbers. No exact small, medium or large hand score is assigned. Buyers at either size extreme should treat fit as conditional.
Gaming Use
The Viper's low shell weight and restrained controls align with aim-led competitive games. Wireless report-rate choice is a system setting, not evidence that an FPS player will perform better at 8K. General gaming and keyboard-heavy MOBA layouts can use the same controls. A large MMO action bar remains a distinct reason to select a multi-button model.
Connection & Battery Conditions
Razer lists receiver-based 2.4 GHz wireless and wired operation with USB-C charging, without Bluetooth. Claimed runtime is up to 95 hours at 1K, 62 at 2K, 40 at 4K and 17 at 8K. These are manufacturer estimates rather than PeriphPick measurements. The included HyperPolling receiver is part of this model's package; do not substitute accessory requirements from the Viper V3 HyperSpeed.
Dimensions, weight, sensor names and maximum specifications describe products. They do not establish an overall winner. Hand and grip assessments need research context. No hands-on testing is implied.
