Which should you buy?
The Cobra Pro edges ahead on the Mars Score (67.4 vs 59.5), but the 7.9-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the Cobra Pro if you carry the device everywhere and weight or thickness has been the deciding factor before. The biggest gaps in its favor are max dpi, weight.
Pick the Aerox 9 Wireless if you care most about buttons and battery. Its strongest claims are buttons, battery.
Both ship with comparable polling rate, wireless, so those specs don't separate the two — focus on the differences below.
