I live and breathe Stihl but for chainsaws its Husky all the way. If you want a saw that flat rips for your intended application check out the Husky 346XP.
Basically the same thing here, I love Stihl equipment of any type as well, though I very much prefer the Jonsered saws over either Stihl or Husky simply based on ergonomics between Husky and Jonsered, and both will outcut their Stihl counterparts HP for HP. I know that Husky now owns Jonsered, but at one time they were both owned by Electrolux. All the high tec stuff that is available on Husky's (and now even Stihl) came out first on the Jonsered saws.
The problem with Husky's XP saws is that they are designed for guys who use one often, and know how to keep the saw running in the powerband, which is at the top of the rpm range for the XP's. If you lug one down very far, you get out of the powerband and the saw doesn't cut well. I believe that you'd be very well served by the MS290 if Stihl is your preference, but if you are open to suggestions, then try either a Jonsered 2245, 2250, or the Husky 345, 350 series. The Husky's can be found at your local Home Depot and Lowe's. These saws are designed to have a much wider powerband before the saw stops lugging/cutting properly, and are designed with the occassional user in mind.
I have cut with a 290, and it is a step above the others in power, and is a fine saw. It is also Stihl's best selling saw for more than one reason.
I personally own several Jonsered saws now after running Stihl for 20+ years. I have run them side by side on many occasions and it's one reason I switched. Since Husky's have the same parts other than the external facia, they'll do the same thing.
All in all, they are
all very good saws, and you won't go wrong no matter which one you choose.
