I'm trying to think of one of the well known self defense rounds that has questionable reliability and I can't come up with one. In addition the performance difference between the top rounds is negligible.
There's lots of comparisons on YouTube. I don't remember if Shooting The Bull did a .45acp round up but if he did, I really like his comparison tests. He does consistent, quality testing.
Probably the two most popular SD rounds are Speer Gold Dot and Federal HST.
