I trust all of mine once they're set, but I have found each are better with some powders than others.
The RCBS Quick Change does the best job with Universal and Unique at 6gr and less. The rifle insert does well with everything I've tried.
The Lee PPM does very well with stick powders.
The Redding 3 meters ball powders great and stick powders well. I use it more than the others.
The Lyman 55 does everything well except for flake and very fine ball powders. But it's pretty old and there's more clearance between the frame and rotor than there should be...
