Pressure vs temp, butane runs about 40psi at 70*f and propane runs about 130psi at 70*f
The pressure drops as temp drops. The BTU content is about the same per ounce of liquid, propane bottle needs to be bigger to compensate for the higher expansion and pressure. Butane doesn’t work well for low temp environments due to the lower pressure and is about twice as expensive as propane. Go with the propane
