The differences in handgun loads such as the aforementioned are so minimal, that it's not even worth the debate.
Give me my AR-15 launching a bullet at a screaming 3,000fps.
Handguns are for conceal-ability and convenient packing of a weapon due to it's size. It's a sidearm, a secondary. Not a primary. If it's all you have (CCW) then it is your primary. I wouldn't bet my top dollar that it'll get the job done better than a rifle.
Again, the following mentioned handgun cartridges are very minimal in difference in terms of incapaciation. Shot placement is king, even more so among common handgun rounds.
Sáncte Míchael Archángele, defénde nos in proélio, cóntra nequítiam et insídias diáboli ésto præsídium. Ímperet ílli Déus, súpplices deprecámur: tuque, prínceps milítiæ cæléstis, Sátanam aliósque spíritus malígnos, qui ad perditiónem animárum pervagántur in múndo, divína virtúte, in inférnum detrúde.
