If you want to go alky for two people, be aware that you will need to double the amount of fuel you take. You should check this before you go. And you will need a good windshield and a flat base with the MBD stoves.
Make sure you use ETHYL alcohol ('denatured alcohol'), not the fairly toxic Methyl alcohol which is also available. The ethyl alcohol has a higher fuel value than the methyl alcohol.
I can only comment on stoves I have tried. The Elite II is excellent, although it may be a shade small for two people. The Sketti is very powerful, but needs a wide low pot. The 1.3 L pot is probably OK, but I am not sure of the diameter of the 0.9 L pot.
The Caldera Cone SYSTEM is heavier, but it is a very ingenious solution and solves both the windshield and the stability problems. If you use it, make sure you have LOTS of space at the top where the hot air comes out, and a reasonable amount of space at the bottom where the air goes in. Getting enough flow in both places is IMPORTANT.
Me, I use a canister stove.
