I just spent $60 bucks converting a 455 rancher to run Stihl chain (Oregon 0.050 bar and Stihl 33RSC chain). The stuff that came with the Husky was quite pathetic in comparison. The saw itself is decent enough, but not what the Stihl MS290 is. The Husky is tight around the clutch and therefore difficult to change the clutch. The Husky anti-vibe is quite sloppy and precision cut placement is difficult.
The Stihl 290 was easier to change the bar/chain and performed better (more power, better anti-vibe control). The husky was slightly better to start (also considerably newer than the Stihl 290 I ran).
It is very difficult to get an aftermarket bar for the Husky. Husky uses many different bar mounts and the aftermarket companies don't keep up. I think I am correct in saying there is only 1 aftermarket bar for the 455. Stihl runs essentially the same bar mount on almost all of their saws....and have been doing so for decades. That means you have dozens of options for bars/chains. I run Stihl chain exclusively because I have yet to find anything that matches its oiling and stay sharp abillity.
I was having a lot of problems with the Husky 455 covering me with oil mist. That has gone away since changing to Stihl chain.
I know neither of the Stihl or Husky are the exact model you are thinking about....but I know the only difference in the Stihl is the jug size and assume the Huskies are very similar as well.
My next saw will be an MS361. I own a mid 70s vintage Stihl 031AV now, and have total access to my brothers 455 Rancher. I use the brand new rancher as a backup.
I am willing to bet that you will be happy with either the Stihl or Husky.
