The turret should be much more efficient than multiple single stage presses.

I use a Lee four hole turret. First, I deprime and size 100 cases then hand prime them (very much like a single stage). Next, I hook up the auto indexer and load powder, seat bullet, then crimp w/the decapping/sizer die as a dead pull. You can load a couple of hundred rounds, or so, per hour like this (never timed myself).

The main advantage is that all dies stay set up in each set (mounted on a die plate) and all you do is change out die plates and shell holders.
