I have used IMR4350, and have been happy with that powder. I’ll probably switch to IMR4451 or H4350. I have all three on the shelf. But I liked IMR4350 so much on several different cartridges that I bought a couple 8 pounders when the President between the Bushes was about to take office. I still have quite a bit of the IMR4350.
As far as bullets go I pretty much stay with Hornady Interlocks and Nosler Partitions, though I had a bunch of Remington CL’s and I also shot a box or two of Speer HC’s.

I prefer classic.
