If you are sold on buying a set I would get the Redding competition set. Personally I don't buy dies in set because no one maker has everything I want.
I like the Lee Collet Die to neck size, Redding or Forster seater, Redding body die, for a bushing neck size die I like the Forster because you can also bump the shoulders with it.
Forster would be my first pick and Redding my second as a set. If piecing out I have pretty much went along Forester's direction, except the Lee Collet Die which I will purchase sometime in the future.
