My brother has a MSR Pocket Rocket, I've got a Snow Peak Giga, we used both at the same time last fall at 7500 ft. and right at freezing. His boiled water a little quicker, mine used less fuel, basically a toss-up IMO. I also saw a Jet Boil in action and they work great as well, just a little bulky. I prefer the 230 gram fuel cans, they have a larger footprint and are more stable. Also a piece of heavy duty aluminum foil wrapped around the stove works great as a wind shield and will make it more efficient.
