I currently use Reloader,IMR and Hodgdons powders,and get good performance out of them all.I use whatever powder works best in the particular gun,regardless of the brand.
I use em all myself. Seems every brand has a turd in it. But with that said, it seems Alliant has the most recalls and variations between lot to lot than most. I have litterly got 100fps difference in different lots of RL25.
