WD, check out this test that Sgt.Rock did a while back. There is a cross-over point where liquid fuel stoves gain the advantage over canisters. However, a lot of people here swear by alcohol stoves because the stove itself weighs next to nothing and the fuel can be carried in soda bottles. The trade-off is less energy per unit of fuel with alcohol; i.e. it doesn't burn as hot as white gas.

Unfortunately, this test only compares one canister stove with various alcohol stoves, but it may help. Sgt. Rock's stove comparison
