"most pistol calibers do the same thing" comes with caveats and it's not an excuse to carry weaker ammo.
I wouldn't run .22 or .25 auto, not even .380 because of how unreliable it is in expansion. 9mm hits a sweet spot with all its disadvantages, .40 has a special place in my heart and 10mm is optimal for dropping anything on two feet.
