Which should you buy?
The G502 X PLUS edges ahead on the Mars Score (58.4 vs 55.2), but the 3.2-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the G502 X PLUS if you care most about max dpi and battery. The biggest gaps in its favor are max dpi, battery, buttons.
Pick the EC3-CW if you carry the device everywhere and weight or thickness has been the deciding factor before. Its strongest claims are weight.
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.
