Between the EC1-CW and EC3-CW, the EC1-CW comes out ahead in several specs, while the EC3-CW wins on weight. Overall, the EC1-CW scores 54.7 and the EC3-CW scores 55.2 on our Mars Score.
Which should you buy?
These two are nearly even on the Mars Score (54.7 vs 55.2). The decision isn't about overall quality — both clear the bar — it's about which specific trade-offs fit your use.
The EC1-CW 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 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 max dpi, 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.
