Which should you buy?
The Viper V3 Pro edges ahead on the Mars Score (84.6 vs 88.8), but the 4.2-point gap is small enough that the right pick comes down to which spec advantages matter to you.
The Pulsefire Haste 2 doesn't pull ahead on any single popular-comparison spec — its strengths sit in the spec table groups rather than the headline advantages.
Pick the Viper V3 Pro if you carry the device everywhere and weight or thickness has been the deciding factor before. Its strongest claims are max dpi, weight, wireless, among others.
Both ship with comparable polling rate, buttons, so those specs don't separate the two — focus on the differences below.
Bottom line: there is no wrong answer here — match the spec advantages to how you actually use the product. The Mars Score parity tells you both are well-rounded; the differences are about trade-offs, not quality.
