I'm an all Stihl guy, but I'd swap any saw in my line up for any competitors saw and probably notice no difference at all. I run huskies that belong to other guys prety often and they're just as good. Most pro saws of the same grade are very comparable, and performance differences and reliability differences are pretty minor. The 200T is a saw for which there is no replacement though. It's not a matter of a second of difference, that power, response and handling give enormous control in the tree. Being able to snap, pop, spear and jump branches off very consistently means control, which equals higher productivity and safety. It reduces the need for roping down dramatically. The difference adds up to hours, not seconds.
I've got a few good runners, and one new 200T sitting in a box. I'm still on the lookout for more, and I'm happy to pay whatever price. That saw is my money maker.
If mine all wear out and I can't get more then I'm going the brad mod route. If you haven't seen the vid, take a look. Muff mod, timing advance and a re-tune and the saw looks to out cut a muff modded 200T.
