I like 800X as the operating pressures are substantially lower.

Unless cost is not a factor for you, I'd use the powder that I could get at the least cost per load.
I've used them all for 12 ga. target loads -- Red Dot, Green Dot, 700X, PB, Winchester Super Target, Hodgdon Clays, Hodgdon Titewad, and probably some others I've forgotten. I can't tell any differences in the quality of the loads I produce from them, although some are cleaner burning than others, and some are finer grained and others are coarser. (Red Dot is the coarsest grained -- it takes up more space in the case for a given charge weight -- and also the dirtiest burning. But it is completely reliable and has probably been used in more 12 ga. target loads than any other powder.)
