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:
