124 gr Gold Dots, because they're reliable in my guns, are readily available at a reasonably cheap price, and have impressed me with their consistent performance in actual people.
Whether GS, SXT, HST, GD, PDX, etc.; with similar weight bullets, all of the standard, well-known stuff works pretty much the same in people. Even the off-brands are very little different from premium brands when it comes to the actual wound.
If it's reliable in your gun, I'd go for whichever ammo I liked best (for whatever reason), and not worry about it.
