The fuel's weight is not as relevant as the total combined weight of the stove, fuel, and fuel container that needs to be carried at any given time. Also it is time between restock that matters not trip length. That total weight works out to be less for alcohol for me for in the neighborhood of 10 days or less between restock and lighter for other fuels for longer than ten days or so between restocking. That assumes my typical usage, the time period where it advantage shifts would be different for different usage patterns.
So yes the fuel is heavier per btu, but whether the load carried is heavier is a different matter and the one that actually matters.
