I wouldn't put much stock in any priming system that's part of a press. Using a hand priming tool is exponentially faster and allows much greater consistency.
JMO - Turret presses are an unnecessary gimmick. Consistency is truly your friend when it comes to reloading. I've actually watched guys rotate the dies around the ram one round at a time and the results at the range were ... well, let's just say "not terribly impressive."
On the other hand, if you have 100 or more empty .30-06 cases laying around that justify a reloading session and you have a set of .30-30 dies set up in your turret press, you're going to dismount and re-mount exactly as many die bodies as you would if you were using a single-stage press. It's really more a matter of whether you want to do the setup all at once or at the beginning of every operation.
