More power is subjective, I think. Echos usually lack chain speed in the high end bands, which can translate to less power. An example is the cs680, at 66.7cc with a 20 inch bar it'll most likely cut behind an ms261 in 12 inch wood but the same saw will still pull a 36 inch bar , buried better than an ms400. Just depends on how you run the saws. I find Echo saws a pleasure to run, even after running all the other latest and greatest Stihl and Husqy stuff. Some people hate them. I talked to a guy the other day who hates Stihl and loves Echo, most likely because he learned on Echos. It's subjective.
