Hunting and camping are totally different uses than long term survival. two different things, with different strategies...
Small gas stoves: Love 'em. If you are back packing in for hunting or camping, that usually means a few days, week at most. And you are carrying it. Weight is paramount. I won't carry propane for this: The 1 Lb canisters are steel and heavy. small Isobutane are way to go. the stoves are tiny, work well, and weigh nothing, and the Iso canisters are light. If you are going in by canoe, or other conveyance and weight isn't as big an issue, and you are in the woods for longer, a small Naptha stove, using white gas, may be better. When you start needing 8, 10, 12 isobutane canisters, there is a point where liquid fuel becomes more weight efficient... I have a small, single burner, pump pressurized naphtha stove, and it not too bad weight wise. Carrying a rocket stove is big, bulky and heavy by comparison. And fuel, while everywhere, is often very wet.
Survival: fossil Fuels run out. Period. There is fuel in nature. Use it. The rocket stove wins. But its not something I would take hunting...
A third option?: The best intermediate, "Oh shit, it's longer term SHTF" concept may be the liquid fueled, multi fuel stove. It not as omnivorous as a rocket stove, but easier to feed. No smoke to give away your position. Quick to start, rapid to cool, pack and haul ass. Easy to feed. My little pump pressurized Coleman single burner is a multi fuel model, and will run on unleaded gas. While Isobutane and 1lb cans of propane can become scarce, regular unleaded gasoline is farrrr more common. And Im not trying to find it 20 gallons at a time. A quart of gas is a lot of cooking.... other stoves will burn just about anything from gas, to keosese to diesel. These burn a bit dirtier, but are cleaner than burning wood. (less smoke). These are probably an ideal option.
