White gas stoves plus fuel are a lot heavier. Most people carry them only for winter use, when cold temps make isobutane (not propane, although there's a little in the mix) unreliable.

White gas stoves also have to be pumped. In the 1980's I went on a group backpack and took a MSR Whisperlite (white gas) stove. Everyone else had canister stoves (Bluet was about the only kind available back then). Invariably everyone else was through eating before my water boiled! Needless to say, I switched over, too!
