Of course, Stihl and Husqvarna are regarded as the top of the line saws, and the others are usually ranked after that.
However, I have an Echo weedeater that is 21 years old, has never had any maintenance, and it runs like a top. Unbelievable, the ruggedness and reliability of this Echo tool.
I have heard a lot of good things about Echo tools and I bet the Echo chainsaw is a real nice saw.
