If you're asking about brand names one is about as good as the other. I prefer RCBS then Lyman, Pacific or Redding. Those three appear to be of equal quality to me. C & H, (if they're still in business), makes a good set of dies. There's nothing wrong with Lee dies, and I own three or four sets, but they're always my last choice if others are available.
Regarding the crimp, a roll crimp is the way to go in my opinion. Just roll it into the cannelure of the bullet you're loading. I use a taper crimp on one smokeless cartridge I load for. I use a light taper crimp on everything I load for my BPC rifles but they're all single shots.
