Most name brand stove are pretty good. Duane is our local stove expert, I'm sure he'll be along with some valuable info. It also depends on your use, winter camping in sub freezing temps calls for a inverted canister or for you to warm up your canister prior to use. Look at BTUs, pot supports, and flame distribution. A small flame distribution is good for narrow pots while the reverse is true for wide pots. A good valve so you can simmer is also nice. Another thing to think about is effiency, a efficient stove may be worth a bit of extra weight as long as you save that weight in fuel. Depending on where your hiking you could also consider alcohol stoves and solid fuel like esbit.
