MSR's PocketRocket Series has long been a favorite of backpackers looking to save weight. Our pick of the bunch is the PocketRocket Deluxe, which has a larger burner area (spreading out the flame, and leading to faster boil times and better fuel efficiency, especially with larger pots), and fared better in the wind. The genius of the deluxe model is the small curved lip around the burner, which helps keep wind from getting to the base of the flame. It's a small difference, and you still want a windscreen. But it's enough that over the long term I found it more effective at maintaining a simmer in the wind, should you want to do any actual cooking. The deluxe model also features a piezo igniter. I would still carry a lighter, but it's nice to have the igniter switch option to quickly relight it.
The PocketRocket Deluxe works well as a stove for a solo traveler, but the larger burner head also makes it great for larger pots, like a 1400ml, which is plenty for two. Anything larger than that and all fuel canister stoves like this get a little unstable. You can do it, but the risk of your food ending up tipped over in the dirt goes up. For larger groups, I suggest pairing off in twos for cooking purposes, or go for a remote canister stove like the MSR WhisperLite or Firebox stoves below. It's collapsible and stores pretty well, though it is .3 ounces heavier and slightly taller (.2 inches) than the PocketRocket 2, which means it might be a tighter squeeze fitting it in some pots.
