Where are you going for the trek? This could affect available fuels...
What altitude are you walking at? This affects fuel performance...
Stoves are a personal choice...what one loves, the next hates.
Trangia are self contained and hard wearing...get a gas conversion and you have the best of all worlds.
If in an area of iffy fuel availability, then it has to be a multi fuel.
I wouldn't consider the jetfoil unless you only cook simple, boiled, food. It is a one trick pony unless you buy the adapter and frying pan.
