Huskies rev high but less torque pulling through big wood. Stihl has more torque less rev.....Last 10 years Stihl's quality has gone way down, especially the new models. Got a few 36's for fire and they only lasted a season , half fell apart and half needed top end rebuild.
Generally easier to change sprockets and clutches on a Stihl.
I've owned Stihls but always liked Husky better. My work saw is a 372XP with a 32" bar and my personal saw is a 359 with a 24" bar, both have been run hard and have been excellent.
Huskies are lighter for the power and the handle bars are more ergonomic.
Your new saw should be good, if your cutting a ton first thing I would do to it would be a 24" bar, adds a little weight but saves your back from always being hunched over
