Here are my additional criteria that caused me to make a couple of switches in my cooking system:
* Easy re-light - I do a lot of meals where I need to use the burner for a while, then off, then re-light to cook something else. I found that white gas did not re-light cleanly. I always ended up with trouble lighting, then a sooty flame on the second pass. Waiting until cool, all was fine, but not practical. This alone was just about enough to make me switch to propane.
* Decent simmer control - lots of heat is great for boiling water. And burning eggs. Really can't stand overcooked fish, etc. This is where my cheaper Camp Chef propane stove let me down. Maybe better stoves do this better, but I've found one more criteria that put me into a third category:
* Quick setup and tear-down. In my rig, my gear is usually stowed between meals. We don't tend to "base camp" for days at a time. Either because we're on the move, or away from camp in questionable security circumstances, or whatever. The fact remains that the process of re-attaching the fiddly small-thread adapter into the side of my propane stove was a major headache.
My solution was almost an accident:
On a last minute solo trip, I groaned at the idea of lugging the 5lb tank and stove I don't like just to make ramen, so I threw the little butane catering burner I keep for emergencies into the chuck tote.
What a revelation. Easiest setup (one lever to lock the cartridge), one click to light, great simmer control and decent overall thermal output.
I've since sourced a similar single burner from stansport that will run on either butane cartridges or 1 lb propane tanks with an included adapter. I'll use butane when I can, and the ubiquitous propane cylinders on the rare event I can't source more butane.
I tend to rotate my second heat source between the other butane burner, a propane grill, or a charcoal grill, depending on menu, length of stay, etc.
As a bonus, the basic butane burners are usually sub-$20 at my local Asian market and the trick dual fuel version was like $35 at Wally world.
Hope that helps.
