H335 is my go-to for just about everything .223.
Fallbacks would be H322, Benchmark, CFE223, AA2230. I haven't tried Win 748 but I think it belongs on the to-try list. I'd stick with spherical powders unless I'd tried all of them and none worked well. Then I'd weigh trading in the gun vs cylindrical powders.
I haven't tried H322 but I have the rest of your list. In the same burn rate as H322 is RL10x and AA2015. I have had very good accuracy from both of those powders. As per the loading manuals the velocity if typically less than the slower burning powders. But, accuracy is among the best. The worst accuracy is Win 748 in my experience but I have a bunch of 748 on hand.
