rowlapa1974 meths burner/hexi cooker.
Never really done meths, watched a few torch tents with leaky fuel and careless practice.
Have never costed out meths over gas.
Meths can be put out easily in trianga type burner units, small, easy to carry, easy to light, easy to get fuel for.
Hexi cookers or non MOD the Esbit solid fuel cookers. Not as versitile as meths but on a par for cooking, hand full of dirt/sand puts out a fuel block, needs more care for scorching (try cooking inside a tent with Hexi/Esbit 🙂 )
Harder to find fuel than Meths & gas.
Consider alcohol gel cookers, although finding fuel can be tricky compared to meths/gas.
Done Hexi/Alcohol, MOD and Civvy, it works with drawbacks, Esbit burners are silly light.
Gas. Easy to get cans, loads of choice on burners, clean burn, easy to use, works well within UK climate (not so at extreme sub zero temps or high altitude)
Gas for me, drawbacks, weight and volume of gas cans, offset by fast clean burn times, with “care” can be used inside a ventilated tent.
Safe and easy to use, loads of choice on burners, even the cheap MSR Pocket Rocket clones are good, just don’t expect a 10-20year hard use life span from clones.
Petrol-multifuel burners, for serious subzero climates or extreme altitude and third world adventures where finding gas cans and meths may be a major issue.
Set a budget, set a useage area. Do you need ultra light weight ? can you live with the limits of that cook system ?
Gas is bulky in volume, but quick and easy to use, fairly clean, easy to pick up fuel and work with.
