Im a bit of a stove lover, so I have many many stoves. You can't go wrong with any of these. However, there's a few things of importance:
Jetboil, MSR wind burner, any of those cartridge style are compact and easy to use. however cartridges are expensive for the amount of water they heat. While the jetboil and the MSR with the fins and rings are more efficient, the cost difference can be quite large, and will take in the neighborhood of 15-30 cans of fuel to recover the difference in their price (such as a pocket rocket (30-40 dollars) (basic, no frills, add a cup/pot for 5-10 dollars) vs the cheapest jetboil (about 80 dollars, comes with a cup)there's still a 30 dollars difference there, which is about 5 230gr cartridges.
Every single one I found in the U.S. has been a blend- either a tri blend or a dual blend (blend of propane/butane, usually coleman brand) or the tri blend (usually the Jetboil/msr/primus/snowpeak brand)
If you google a guy, "hiking jim" he does a lot of stove reviews, as well as how long it takes to boil water for each stove type, and how efficient each one is.
I have the original reactor- when I wen't backpacking, morning temps were in the low 30's (we had snow on the ground overnight). The Jetboil was sputtering and took forever to boil water- I ended up boiling over 2.5 liters of water before the jetboil had even boiled water. Sure, there are ways you can coax it (heat up the cartridge, put it in a pan of water, etc), but the Reactor is the pinnacle of fuel cartridge technology in my opinion, without going to the inverted setups. That I have not personally tried, but I hear they go down way lower in operating environments.
Reactor however, sucks at simmering. I hear the windburner is much better.
However, my most used setup is the snow peak giga. It packs into my titanium cup, with a smaller 110 cartridge. its tiny, portable, and flexible. I can easily clean and wash my cup. I can put it on the fire, I can rinse it, scrub it, its titanium. I've used this thing quite a bit, even when just road tripping locally. Find a rest stop with a picnic table, and in a few minutes, I have boiling water.
I boil water in the morning for coffee, and put it in its own thermos. If I finish and want more, I'll boil more.
