I think the answer is going to hinge on "Which powder can I find" rather than "Which would be a good choice".

Primers seem pretty available. But powder hits the shelves (real or web based) and then gets bought out in literally minutes.

I carry a list of acceptable powders with me (text file on my phone). Any time I'm in a place that sells powder, I check the list. I buy powder if they have it and it's on the list.

I have a lot of powder on back order. I'm on a lot of "notify me" lists. I spend a lot of time on GunBot.

Buy it when you can, anything suitable. Load it up. Experiment with low to medium loadings. Take notes etc. When you find one that you think you like better than the others, get on the backorder lists for big jugs of that brand.
