Both excellent saw brands- all depends on size, your intended uses & what type of timber you want to cut.
As general recommendations buy a slightly bigger than smaller saw than you think you'll need, don't be talked into too big a bar (with experience/thought you can cut at least double the bar length less c2inches without drama), watch the operating weight as only a few extra lbs can make long operations a workout, make certain the chain oiler is adjustable, for longevity get a bar with a greasable bar sprocket, dismiss any saw with a "quick twist" chain adjustment - stick with the proven screw/2 nut adjustment, run the saw on premium 2 Stroke @ 50:1 non-ethanol fuel/good bar oil/clean filters/& a sharp properly adjusted chain....& it should last at least c.10yrs+) & wherever possible fit a rim sprocket rather than a spur drive sprocket.
In smaller general duty saws (50-65cc) for general farming, rural fencing & breaking down firewood/limbing/felling trees (@ up to c. 20inch trees regularly & occassionally larger) I prefer Husky's, where a larger saw (70cc up) is required for felling bigger trees or breaking down large timber I prefer Stihl (MS381/460/660/880).
My personal preference for general lighter rural duties if I had only 1 saw would be:-
a) Husky 455 or 460 (55--60cc) fitted with 18inch bar & probably a .325pitch chain (in ieu of 3/8 pitch). The .325 is the "safest"/most versatile combo (well only as safe as chainsaw can be), an 18inch bar will take down the occasional c.30inch hardwood tree & the .325 will minimise kicking/kickback ( & despite what the "shop experts" say,if kept sharp has no trouble cutting through dead hard woods - handles dead Australian hardwood no drama) & cut or carve without drama for the operator
b) or as a step up in size if you're only cutting hardwood or larger timber Stihl MS381 (72cc) rugged reliable, low tech & good value, or a Husky 562 (59cc), but to make best use of the power you'll need a 3/8"c.20 inch bar combo
IMO, rightly or wrongly, the Husky in small saws fire up far easier & their startup/shutdown controls & maintenance are more intuitive for operators, nothing against Stihl's it just seems small Husky's are just a tad marginally better in these areas......our 455's have 2litres+ (close to 2quarts+) of 2stroke oil run through them @50:1 a year so they're workhorses.
We own/operate all the above saws & more on our farms, & with 35yr+ professional rural chainsaw use & logging experience, like most I have favourite saws - unfortunately the US McCulloch PM850's/1000's became extinct in the early 80's, but then I'm not quite as fit as in the late 70's/80's to operate a .c10kgs/20lbs saw all day long...but I still keep a few in running order for occassional use like the PM1000 & PM805 below........
