This has been discussed here a few times and those threads had links to video comparisons of a variety of saws. In earlier tests, DeWalt was the top performer. In later tests after Echo introduced their saw, the Echo edged out the DeWalt.
Based on that, I bought the Echo which is a 16" 58v saw. It takes standard Oregon bars and chains so an 18" bar is easy to do. I bought a 14" bar for mine thinking the 16" might be too long for my SxS. I use a gas Husky for firewood and the Echo goes on the SxS and camping for lighter use. I've been quite impressed with the Echo...
