Somehow I missed this thread but I'll put in my 2 cents anyway..
The best chainsaw in my opinion, brand not withstanding, is one that starts on the first or second pull, runs a long time with little upkeep and didn't cost an arm and a leg to purchase.
I just happen to own a few saws myself plus I grind saw chains and sharpen
chipper knives for local arborists.
My all time favorite long lasting saw is the Stihl 028 I bought when I was about 22 and I'm 75 now and it's still running and cutting like a scalded dog. Matter of fact, I just replaced the original spark plug. The original one still looked good, believe it or not.
For the last 10 years or so, all my saws are run on canned fuel, in my case Echo Red Armor 50-1.
I'd say my ancient 028 is my best saw but I also own a couple Echo's, a CS top handle Arborists saw as well as a 590 Timber Wolf or Bear or whatever it;s called and a Stihl 075 and a Stihl 090. The last 2 are devoid of fuel and oil and just sit on a shelf. Too heavy for this old man to use anyway. Bought them both new when I bought the 028, many, many moons ago.
Far as I'm concerned for value, you cannot beat an Echo, the new Stihl's are over priced and I don't care for their fuel injection either.
Like I said, the best saw is one that starts on the second pull and runs forever and of course a sharp loop makes or breaks any chainsaw..
