I do mine on the press. I have a Lee turret. I have only had it a short while. I find that I like decapping and sizing all the cases prior to cleaning them, then I put the press into continuous mode and prime, powder, seat and crimp. At the point I put them back in the press after cleaning, I only have to touch the case once. I like the lever prime system that Lee has on their newer presses. If I were using a single stage, I would probably go with hand priming. I thought about the auto prime system they sell to go with the turret. It looks awkward to me from the videos I have seen.
FWIW, I am a woodturner and made a small wooden bowl. Very shallow, with a thick bottom (for stability) and a thin lip. This allows me to easily dump primers onto it, and slide a single primer off the edge. I occasionally drop one as I am putting them in the cup on the press, but after doing it a while, I find I do it less and less.
