I have used every type of stove out there and they all have their place. I use white gas for winter backpacking, alcohol for short, ultra-light back packing and as a back-up to canister stoves on tour.
My go to system is the Primus EtaExpress, similar to the Jet boil and about $40 cheaper. boils water in about 2 min. and the smallest canister (the jet boil canister) has 60 min of burn at 3/4 flame, the large canister has 3 hours of burn, that's a lot of cooking. Most of my cooking is using the freezer bag method, so I'm just boiling water, but I also do eggs in the lid over boiling water. Freezer bag cooking really conserves fuel.
