When the cartridge allows, i use two different brands. I have really been impressed with the Whidden click-adjustable sizing dies. RCBS Matchmaster seating dies are mostly what I use, now (I like the bullet feed window).
I’m a big fan of the Forster dies. You send the sizer in with a fired case and they will custom hone it for you. All the upper end dies are worth it to me. Rcbs match, Redding type s. Ive never regretted buying them and have always seen improvements
I've had superb luck with Redding, Lee, and Hornady. I will die on the hill saying RCBS dies are garbage. GARBAGE. Two different rifle die sets neck tension was so loose after sizing you could turn the bullet in the neck after seating. I also had trouble with the pistol set in 50 ae. It didn't size the case nearly enough for bullet tension, so even after taper crimping gobs of unburnt h110 were coming out of my desert eagle.
Redding Premium Deluxe 3 die sets are my preference (centerfire rifles at .4 - .75 moa accuracy). Tempted to try the Type S bushing series, but I'm not convinced it would be worth the money for what I do (reloading for hunting at average to moderate distance).
