Product 2: Razer Viper V4 Pro
No score yet
dock compatibility
Product 1: ASUS ROG Spatha X
4.8

The dock is central to the experience, acting as charger and receiver while seating the mouse easily.

1.5

Reviews explicitly note the absence of a dock or dock compatibility. That omission stands out because the rest of the mouse is positioned as a premium flagship.

DPI range
Product 1: ASUS ROG Spatha X
5.0

Multiple reviews highlight the 19,000 DPI ceiling as one of the mouse's headline specs.

Product 2: Razer Viper V4 Pro
4.9

fingertip grip comfort
Product 1: ASUS ROG Spatha X
1.5

Fingertip grip is explicitly described as a poor match for this mouse.

Product 2: Razer Viper V4 Pro
4.6

Fingertip grip is also highlighted as a good match for the Viper V4 Pro’s low-profile symmetrical design. Reviews regularly list fingertip among the preferred grip styles.

FPS gaming suitability
Product 1: ASUS ROG Spatha X
2.3

FPS suitability is a weak point, with reviewers citing the weight and slower feel for twitch play.

long-session comfort
Product 1: ASUS ROG Spatha X
3.0

Long-session comfort depends on fit: MMO sessions can work well, but the weight also causes fatigue for some users.

Product 2: Razer Viper V4 Pro
4.7

Low weight and balanced construction help reduce fatigue over long sessions. Multiple reviewers directly connect comfort over time to the mouse’s light, well-distributed design.

macro support
Product 1: ASUS ROG Spatha X
4.5

Macro support is present through the software, which reviewers note can record and assign macros.

materials quality
Product 1: ASUS ROG Spatha X
4.5

One review specifically highlights the sturdy plastic shell and shaped metal base plate.

Product 2: Razer Viper V4 Pro
4.9

polling rate
Product 1: ASUS ROG Spatha X
3.5

One review notes a 1,000 Hz polling rate, treating it as adequate but less impressive than some flagship expectations.

Product 2: Razer Viper V4 Pro
4.8

True 8,000Hz polling is a recurring selling point across the reviews. Several reviewers say the higher polling rate improves smoothness or responsiveness, even if some note the benefit is strongest for competitive play.

portability
Product 1: ASUS ROG Spatha X
2.5

Portability is mixed: the pouch helps, but the mouse's size makes it awkward to travel with.

Product 2: Razer Viper V4 Pro

4.5

The large number of remappable buttons is one of the Spatha X's main selling points across reviews.

Product 2: Razer Viper V4 Pro
4.5

Reviews confirm that the side buttons can be programmed. The mouse stays minimal on button count, but the available buttons are still treated as configurable.

RGB features
Product 1: ASUS ROG Spatha X
4.5

RGB is a major focus, with multiple lighting zones on the mouse and additional lighting on the dock.

Product 2: Razer Viper V4 Pro
1.8

Product 2: Razer Viper V4 Pro
4.6

The safe symmetrical shell is widely described as comfortable and easy to adapt to. Even reviews with ergonomic reservations still treat the shape as broadly successful.

side button quality
Product 1: ASUS ROG Spatha X
2.5

The side-button cluster is divisive: reviewers liked the idea but often found it cramped, awkward, or inconsistent.

Product 2: Razer Viper V4 Pro
4.4

Side buttons are generally seen as easy to reach and unusually good for a lightweight competitive mouse. Several reviews specifically praise their tactility or usability.

software stability
Product 1: ASUS ROG Spatha X
2.5

One review reports finicky software behavior during setup and use.

Product 1: ASUS ROG Spatha X
4.5

Switch feel is generally positive, with reviewers describing the buttons as responsive, tactile, and accurate.

Product 2: Razer Viper V4 Pro
4.7

The Gen-4 optical switches are usually described as tactile, crisp, lighter to actuate, and responsive. Even reviewers who questioned the sound still tended to praise the core feel.

value for money
Product 1: ASUS ROG Spatha X
4.3

Value is mixed-positive, with reviewers saying the high price is partly justified by the included features and extras.

Product 2: Razer Viper V4 Pro
3.5

Reviewers agree the V4 Pro performs at a premium level, but many still flag the price as hard to justify for non-competitive users. Value is strongest for buyers who specifically want top-tier lightweight FPS performance.

weight
Product 1: ASUS ROG Spatha X
1.9

The Spatha X is consistently described as very large and very heavy, which strongly shapes its appeal and drawbacks.

Product 2: Razer Viper V4 Pro
