What round for SD?
Start with one that functions reliably in your gun. Everything else is secondary.
People can split all the hairs they want, but it's quite likely that any of the standard SD rounds available will do the job just fine. "Oooo look, an extra 1/4" of gel penetration, way cool. Pretty expansion petals too. Gosh."
Uber tactical guy's Ultra Gnarly Nitro Operator Turbo SRT/STi +P+ isn't probably all that much more effective than a humble box of Winchester Ranger when it comes to actual use.
I maintain that a bad person center punched with a modern self defense round will be unhappy. The degree (& duration) of that unhappiness will be more dependent on the marksmanship that delivered it than subtle nuances of bullet design or differences if 40 or 50 FPS. YMMV.
