Alcohol stoves certainly have their advantages but only really for trips lasting less than a few days, where the weight can be minimised by tuning the fuel weight. Alcohol stoves are very cost effective as well. Going for a heat exchanger pot to increase the overall efficiency of the rather poor specific fuel energy capacity of alcohol fuel might well be worth it as well but this would I suspect be marginal when compared to a wide base Titanium Pot with lid.
Again its the story of capability over carry weight. This is mostly defined by the type of outdoors activity and the weather conditions that can be expected. I have tried very lightweight Ti alcohol stoves but have been disappointed as they are just too tricky and fiddly to use in poor weather conditions.
