The laws of physics are a bit hard to argue with. Here's the foot/pounds handgun calibres produce in Corbon DPX, which the stopping power guru Evan Marshall says 'is simply the best'.
Whether you agree with him or not, you can see that the major calibres of 38 Super Auto + P,.357 mag, .357 sig, 10mm, .40, 45 Auto + P and 400 Corbon, don't actually have that much foot pounds between them.
And the 9mm + P isn't a huge way behind (15% between it and the .357 Mag).
And as has often been said; the only thing the different schools of stopping power agree on is; you have to actually hit the target to achieve anything. Carry the most powerful you can hit something with, if you are going with a firearm.
