In the trees I have used stihl, husky, solo and echo. I have used poulan but we all know its not worth mentioning
The echo represents the best bang for your buck, half the price of the stihl, while being more ergonomically styled and being lighter. Tough little saw, you could drop it from reentry from space and it would be okay. Power, longevity and bad air filter let it down a bit, but it represents such fantastic value for money.
The 019 is a great saw until you have to use it, its comparative in price to the echo but isnt worth the lanyard its clipped into, its got the fast ass end of the 200 without having the tit to make up for it (tit is slang for power down these ways). Seen them last a month in pro hands before having issues.
200, Great saw, but for its price it should ???? well be, its a terrible shape, just square enough to get hooked up on everything, its like pulling a reluctant overweight dog on a leash at times. Saying that its the saw I use most, good power, I run a 15 bar for taking down the bigger stuff to avoid lugging my 44 around. But for the money it should be better.
Solo, someone handed me one that was a month old to use, probably would have been alright if it started. Nice and light and REALLY quiet.
335 Husky-the old ones sucked, the newer ones are better (kinda like the M16) Great peak but can be hesitant, great ergonomics. Price is pretty high as with the stihl, but its has some great features.
My choice would be the 200t in a 335 shape with the echo price, and while someone is getting that sorted I would also like a monkeys tail to help in climbing.
