I have to assume you have yet to load on a Lee Classic Turret with the Safety Prime and Pro Auto Dick powder measure. Those two additions to the turret with the auto indexing make that press pretty high volume. When you add in having to hen peck your primers in to the rods and the occasional hang ups you inevitably get on a progressive press that makes the Lee Classic Turret feel that much faster. I load .45 ACP on a LNL AP and when it's running right it's like lightning and I assume the Dillon 650 runs just as fast with the 550 coming in a close second. But they are all an awful lot of automation that gum up from the first misaligned case, primer misfeed, spilled grains of powder, or whatever. I'm not sure I've ever had the Classic turret gum up and come to a stop. And it's pathetically easy to stop between stations to check powder or make adjustments to anything. Granted, the RCBS turret press will be easy to setup the various stations with the Uniflow mounted between them, but you can’t have auto indexing, you have to do the typewriter reset after each loaded cartridge, and extra turret heads are not very quick change at all nor are they cheap by any definition. But like most presses it will make good ammo.
