Hello. I've been very favorably impressed in both 9mm and .45 ACP with Golden Saber and Speer Gold Dots.
I also continue to have good luck with some "old technology" rounds like Federal's 9mm 115-gr. JHP and their 230-gr. JHP in .45 ACP. These do not routinely "pass" the "4-layers of denim test", so if that's a major concern, I'd go with one of the more modern "premium" rounds.
Probably, the "best" in these two calibers remain in the Winchester Ranger T line. I prefer the 127-gr. +P+ in 9mm, but some pretty respected folks advise the 147-gr. is just as good or better. In forty-five, I like their std. pressure 230-gr. load. How much "better" these loads are than Golden Saber, et al, remains an open question with me, anyway.
Best.
