Of course a 460 has more horsepower, it had more power than a 440, its the difference between an 044 and an 046.
I own a 441, my buddies all have 441's. They are the best saw's we've ever used. We pool a 460 and a 660 for the big big tree's and they only get ran long enough to get the tree's manageable with the 441's. We ran 25" bars for awhile, but got smart and figured out instead of bending over a little to cut wood we'd stand straight up and use a 32" bar. Still cut the same size wood or so but the 441 pulls a 32" without problems.
If you want your body to be worn out at the end of the day then run a 460. they are big powerful saws, but they are LOUD, and they vibrate like hell. If you want creature comfort run a 441 and you'll be able to cut a lot longer and burn less fuel to cut the same amount of wood. 460's were great saws, but they are old technology without strato motors and no anti-vibe. If thats your cup of tea power to you but for less money and better comfort you're much better off.
BTW, I'm looking forward to buying a 661 or 461 whenever they decide to put them on the market. The anti-vibe and the fuel savings they'll get will make them the difference in their models just like the 440 and the 441.
Rant over.
