I use a lot of Lee dies and a lot of people do not like the rubber o-ring that locks the die. It can shift and cause problems. Once I removed my Lee .223 sizer from my old Rockchucker press and didn't get the Lee set just right. The cases did not want to cycle in my son's AR 15. The o-ring lockup was designed by Lee for their turrets, so all works well.

Since I load for 5 pistol calibers and at least 12 rifle calibers, I made the choice to buy the Lee Classic Turret press and extra 4 hole turrets. Now I have 2 sets of rifle dies adjusted correctly in each turret. It is simple to turn the turret about 1/16 of a turn and they pop right out. The convenience is a real time saver and there is no chance of getting the dies out of adjustment.

And the Lee Classic turret press is an absolute brute. It is at least as strong as the RCBS.
