They'll all work for cutting the occasional 10" tree. Getting an ms261 to do the kind of work you're talking about is like getting a Ferrari to commute to work, an F350 to haul your fishing boat, or putting a Swarovski on a squirrel gun. You can do it if you wish, but it ain't necessary unless you like to spend big bucks, wanna work part time as a lumberjack, or heat your home with wood only. I tinker with these, because I pick them up cheap and like to work on them, and they're easier to store than old motorcycles or cars. I've got about 10 more laying around in addition to these...
