I need an "All of the Above." I have more than one set of dies for most calibers and use bits of each, or whole sets, depending on what I'm reloading, but I also adjust those dies back and forth as well. For example, I use Hornady's sizing and expander dies for .45ACP/AR but use Lee's powder through die after they're expanded to get powder into the cases and Lee's FCD for crimping. I also use bits of Lee's .455 Webley and Hornady's sets for .45ACP when making .455/.45 for my shaved Webley. I mix and match dies to do what I want and adjust as needed. Same for .44Spl/Mag, .38LC/Spl/.357Mag/Max, .32S&W/S&W Long/Colt New Police/H&R Magnum, etc. so I have .32ACP seating and FCD but use the .32S&W sizing die.
