For a canister stove? Snowpeak or MSR work okay. They work better if you stand the canister in a dish of water, or put it on a foam base or something to keep the canister off the ground (or the snow). Putting the canister in a pocket and/or in the sleeping bag helps too.

All isopro stoves are less efficient in the cold.
