Lamzu - Maya X vs Razer - DeathAdder V4 Pro

These two are nearly even on the Mars Score (89.1 vs 90.5). The decision isn't about overall quality — both clear the bar — it's about which specific trade-offs fit your use.

Pick the Maya X if you carry the device everywhere and weight or thickness has been the deciding factor before. The biggest gaps in its favor are weight.

Pick the DeathAdder V4 Pro if you care most about battery and max dpi. Its strongest claims are battery, max dpi, buttons.

Both ship with comparable polling rate, wireless, 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.
