I'd stick with the three manufacturers you've identified. All three are rugged -- if you stay away from the "home owner" series. All three have great parts support.
I've been cutting about five cord a year for about 35 years now, but I've been using them for nearly 50 years. Chainsaws last me about 15-20 years.
For the last three seasons, my trimming saw has been a Husqvarna 2.7 hp e340 with a 16-inch bar. My bucking saw is an 3.5 hp e455 Rancher with a 20-inch bar. Both have been trouble free, and both usually start on the 1st or 2nd pull.
The only complaint I have is the chain recommended for the 455. It also came with an extra chain -- so I have two of them. Because of the multiple angles, I cannot sharpen it with my electric sharpener. I'll change over to a different type of chain next season.
