I've had the same MSR Whisperlite, same design, for decades. White gasoline is readily available in the US, and I think you can even just use regular unleaded motor fuel, but additives might gum it up eventually. MSR makes a "universal" model as well, which can burn a wide variety of fuels, most notably kerosene, available in most of the world. The burner is a classic, tried and true design, same principle as the Coleman camp stoves (I still have our family's from the '60s), and you are not dependent on disposable pressurized canisters. The MSR liquid-fuel designs have not changed in decades because they fucking work.
Lately, though, I have been using a beer-can-alcohol stove, open top design, all carried inside a MSR Titan Titanium sub-liter (I think .8 or whatever) Kettle. This is the classic open-top stove design, where the pot sits directly on top, no stand needed, as in this article:

There is no simmer. This is best for rehydrating instant food (freeze dried, etc), making tea, coffee, and the like. It weighs nothing, can be constructed in an afternoon, and is perfectly silent.
