So the best all rounder is
It depends what your priorities are. How much weight matters to you. Ditto size. Convenience. Fuel availability. Performance in windy conditions. How low temperatures are. Possibly performance at altitude. What you’re intending to cook. Whether you’re a gramme-obsessed, twig-burning weight weenie.
Some sort of lightweight, remote canister gas stove with a folding foil windshield and a light-ish pan or two works okay in most situations, a lighter canister-top burner is lighter but less stable particularly if you’re cooking for two people – if you share a stove between two or more, which no-one seems to have mentioned you effectively save weight that way too.
If you’re off somewhere high altitude and remote with dubious fuel availability – Bolivia for example – a multi-fuel thing like an MSR XGK or similar works nicely, makes really good noises and saves you trying to source threaded gas canisters, also a pain if you’re flying anywhere generally …
And then there’s burning gas at very low temperatures where ideally you want both a special gas mix and an invertible cartridge set-up, probably.
Meths is bobbins at altitude btw and generally slow. I don’t think there’s a right answer. Personally I’ve always got on well with MSR and Primus stuff, but you’re not going to find anything that ticks all the STW boxes in a single package ime anyway.
