Which should you buy?
The ULX is the clear pick on raw spec strength, leading by 14.1 points on the Mars Score. The margin is wide enough that the underdog only makes sense if its individual strengths line up with what you specifically need.
Pick the ULX if you carry the device everywhere and weight or thickness has been the deciding factor before. The biggest gaps in its favor are polling rate, weight.
Pick the Cobra Pro if you care most about battery and max dpi. Its strongest claims are battery, max dpi, buttons.
Both ship with comparable wireless, so those specs don't separate the two — focus on the differences below.
