The acetylene flame is hotter from my experience. You will use more oxygen with propane, but oxygen is cheaper than acetylene, as the price has gone way up on acetylene. Propane works fine for brazing and silver soldering. I use my regular oxy-acetylene welding tips for heating with propane. If you use it for cutting you need different cutting tips, and it takes longer to pre-heat to get a cut started.
