Propane btu per gal @60deg 21548 butane 21221, btu per cuft propane 2488 butane 3280, max flame temp in air propane 3595 Deg F butane 3615. Butane is hotter but has a higher boiling point propane -44deg f butane 15 deg f. Due to boil point you are not going to find butane north of the mason dixion line if then. If this is a full time move convert to Propane and buy a DOT approved tank,Your stove should run on propane but you may need to adjust air to the burners to get a good flame consult the manufacturer of the stove. Most if not all LP dealers are going to look at your tank and say they can not fill it do to liabilty (this is the world we live in)
Good Luck
