I've had a Stihl MS 250C for a few years and like it. I cut a several cords of firewood a year on top of osage. I've also gotten tied up with cutting up two massive 4' diameter oaks in my yard over the last few years. (Weekend upon weekend of work.)
I looked at the Huskies and the Stihls. From a layman's standpoint, the plastic choke/kill switches on the Huskies seemed really cheesey. I worried if they used such blatantly flimsy parts there, what did they put inside? That turned me off right away. I consulted a local Stihl dealer about choosing a saw. He steered me towards either the MS250C for the firewood cutting needs I described or a model slightly smaller. He cautioned that the saws (and many gas powered tools) sold in the large home stores are not the same as what dealers carry. Evidently the home store stuff is made with cheaper parts and include a discrete "Service Life = xx hours" label on the sticker, after which the manufacturer considers the saw's engine/parts life over and the saw disposible. (I checked some saws, weed wackers, and other lawn tools in a few of the box stores. Seems true, with 50-100 hour lifespans called out.) Anyway, I bought the MS 250C with an 18" bar. No problems so far beyond a couple times not starting in really cold or really hot temps, and the spark plug wire connection to the rubber boot stinks. (Just a J-hook runs from the spring inside the rubber boot to the wire, so if you pull the boot off too hard to clean the plug, you yank the J-hook right out of the wire. It's tough to get it back in.) I really like the built in twist lock chain tensioner built onto the side of the saw. Super easy to snug the chain up. No hunting or messing with a wrench or boogered nuts. I've used the Stihl many times all day and don't have any trouble with the slightly heavier weight as an old geezer might. ;^)
My father-in-law has a comparable Husky. He likes that it's lighter and made with the soft rubber dampener pads. I honestly dislike the gummy handling of the Husky, as it gives me a sensation that I don't have full command of the saw. It seems akin to ripping around a bend in a Buick with a soft ride instead of an Audi with a stiff suspension. Maintenance wise, his Husky has been pretty much on par with my Stihl.
For sub 16" osage, I think the same MS 250C with an 18" bar would be a great choice.
