Lately I've been analyzing actual carry weight between different alcohol setups (Caldera Sidewinder, Flatcat, white box/bottle stoves, cat can, Zelph stoves etc.) vs the lightest canister setups.
What I keep coming up with is that unless you are using a SUL type system (1oz stove with absolutely minimal fuel carried) to simply heat 2-4 cups of water a day, the intial carry weight of a canister setup is lighter, often considerably so. The alcohol stove systems don't reduce actual carried weight until more than halfway into your trip/halfway to your resupply. At that point you've already reduced overall carried weight (by simply eating your food) to the point where the weight saved by your lighter stove setup is moot,or at least it is to me... Even the SUL setups only reduce initial weight by 3oz or so in a best case scenario, i.e short trip.
Since I like to cook and not just heat water I just don't see any point in alcohol stoves for me, other than fuel availability and the fun of fiddling with them and trying to beat the system (done a bit of that...)
Now of you incorporate wood burning it could change the picture, haven't done any breakdowns on that.
