I have used Lee, Dillon, RCBS, and Hornady dies.
I think Lee dies are OK. I have some that I used for a while to reload pistol ammo and they worked just fine. Later on I switched to Dillon pistol dies because they have some features that I like and work well on a progressive.
For rifle I like the Hornady dies. I have made some really accurate ammo with their dies.
