40 s&w vs 357 magnum?

Question

Which has better stopping power: The 40 s&w from a 4.5 inch barrel or the 357 magnum from a 3 inch barrel?

Answer 1

If you compare 1 round vs 1 round, the .357 wins: simple math. But how may self defence situations are over in one shot? The 40 cal is clearly a man stopper and is more accurate in multiple shot encounters. Now do the math.
