Probably the most versatile powders are H4895, IMR4831, H4831, and H/IMR 4350.
But my reloading room always has a vast supply of RL22, RL25, Varget, and H1000. Oh, and not to mention about 20 pounds of N133!
Ah heck, just mix 'em all up together and call it a Hodgdon 57 mix super powder and that's my favorite!
If it's not far, it's boring.
