In reply to MG83:
Currently using the Optimus Crux, as it has a "flat head" that evening spreads the flames so simmering, frying etc excellent, something a lot of micro stoves don't do, they just char the centre often pot!
It neatly fits into the curved base of a 250g canister. If used sensibly (ie not at full blast) it'll do 2 people for 12 days at 2400 metres. That’s three brews a day, pancakes as comfort food in the evening and a dehydrated meal with smash etc
Haven’t used the jet boil but the weight, cartridge problem and inability to easily make pancakes turned me off!
