I prefer to prime on the press. I also prefer to load single stage as I feel it produces better ammo and fewer mistakes. My priming system of choice is the LEE auto prime 2. I use an RCBS single stage but removed the priming system from it because priming on the downstroke feels 'funky' to me. And loading one at a time into the arm is frustrating. But to each his own.

The hand primers are worth thier weight in gold. Not only because they work, and they do work very well, they are inexpensive, simple to use and maintain and are priceless backups to a press mounted or automated priming system. I primed tens of thousands of cases on a LEE auto prime before deciding to save my thumbs and buy the Auto Prime 2
