I've used most all. While the split ring types are arguably the best to secure a setting, they are not as versatile as the Lyman & RCBS hex style. They will both lock with the brass set screw and can be locked down on a progressive press die plate. Hornady, Forster and Redding are too crowded on a die plate.
Lee O ring type are fine on a progressive when flipped upside down but worthless for preserving settings off and on a press.
