When factoring in actual weight of fuel, not JUST stove and fuel container, I don't feel there is much weight savings with alcohol. There would have to be a serious weight savings for me to give up the convenience of a canister stove.
I feel like the trend to go stove-less has a lot to do with so many people getting tired of cooking on their alcohol stove. For me, a hot meal can really be a mood booster after a long day.
