I have used almost all of them mentioned.Never really used one myself, but an ex of mine used a table top burner that used butane canisters. Apparently in Japan they use them often. Seemed pretty efficient.
I just did a search and you can find dual fuel burners that use butane & propane. Might be a decent option unless you plan to use the 20lbs tanks.
We take a 2 burner coleman when we travel, and it works well but is not light or especially portable. It's a good mix of features and low price. I haven't had trouble running out of gas with it, either. I bought an adapter hose to run off household 20 pounders if needed for SHTF.
I also have a butane and used them a lot in restaurants. they are fantastic! burn clean, nice flame, as good as a one-burner stove on a gas range. Often used in buffets and hotel egg stations. They do use a bunch of gas if you have them cranked though.
I've also used a turkey fryer base hooked to a 20 pound tank, for, um, cooking stuff in big pots (like seafood boils). they are also a good option but you get a big ~1 foot+ ring of fire so not for a small pan or single egg.
