Depends on what you need to do. Hornady FL/seater die sets are pretty good too. Like the sliding pilot for the seater.

If you want to tweak the neck tension as well as setting back the shoulder/body taper to perfection Redding's S bushing neck die and body die work very well. As for seating if you like to manipulate seating depth accurately to fine tune group size, Redding's competition die is a good one. My fav set:

If you are working with a tiny case like the 204 Ruger bullet seating can be a real pain. RCBS's competition seater die has a cut in the side of the body for easy placement of the bullet for seating.
