So, good thing about the Dillon 223 carbide die is that it has a stuck case remover built in on occastion when the case is stuck. The Dillon die has a slight round taper at the die mouth and centers the case better (vs. crushed case mouths). Not so good is the decapper is fixed and bends when you run into a hard to extract primer (i.e. won't budge at all). To continue operation the die must be removed and the decapper pin replaced (takes some time to do).
I've also used Lee Die, good thing about it is the decapper which is fastened by a collet, it slides up until you fasten the collet to the force desired that punches the primers out. If a primer is stuck hard, the decapper is pushed up and can then be readjusted on the spot (faster to correct than Dillon's). Not so good is a stuck case, you have to use a separate stuck case remover. Also the die mouth is fairly straight, I've had occasions when I had to stop and remove a crushed case due to misalignment.
It's a bit of a toss up really :-)
Hope this helps.
