I have a Jetboil, MSR Whisperlite International, and a Snow Peak LiteMax. Have also done the pop can stove, which was kinda fun to make.
If I’m going deeper and weight is a concern, I bring the Snow Peak (1.9 oz, $59) and a Snow Peak 600ml titanium mug (2.8 oz, $35).
For almost everything else, I’ll take/use the Jetboil. I really only use the Whisperlite overseas or on paddling trips due to the weight, but it’s great if you’re in some dump of the world and finding white gas is a problem, as you can burn pretty much any type of fuel in it (kerosene, etc)
