Let's see. I've got Herter, RCBS, Lyman, Redding and maybe one or two more. For me trying to pick a favorite based on using it would really be splitting hairs. My favorite's are based on how they look and are finished. That has always put Redding at the top of the heap but, not willing to pay for them anymore. Recently bough a set of Lee 243 dies and they compare with Redding in finish. Really surprised me. I use a single stage press, have all my life for rifles, no regrets! Try'ed a progressive press some time back, me and it did not get along. Good press just been doing things my way to long and I don't need to turn out a couple hundred rounds in the shortest time possible. First timer at it, I'd suggest either Lee or Lyman. They do every thing the other do but they are not as expensive.
Now does he want the prettiest die's he can get or does he simply want dies that work? I'm a kind of die's that work but more important has alway's been cost and what I can get locally' ha! 70 miles one way to the closest read gun store! If I were a competition shooter as in bench rest, I might consider more expensive dies.
