My option isn't there. I shoot mostly semi-autos but use a turret press. I don't shoot in high enough volume that I really feel the need for a progressive.
My handgun collection is about 70% revolver and 30% semi-auto, and I reload using a turret press. All my life I have shot pretty much by myself
8 out of my 10 firearms are semi-auto. Of the 2 odd balls, one is a bolt action and the other is a pump shotgun. I reload on my 550b. I still have my single-stage Lee that I use simply for depriming. I tried it once just for kicks and ran 100 rounds of 45acp through it. Felt like a waste of time when the 550b did the next hundred in 20% of the time and the quality/reliability is equal. Some may say you have to pay more attention to a progressive but shouldn't your attention be undivided regardless?
As for rifles, I load for my AR and a bolt action. I only use a single stage press. Same goes for my pistols.
If I were loading a very few number of precise and accurate rounds, then by all means a single stage would me my choice. With that being said, I wanted a decent amount of volume, so I upgraded to the turret press.
It's funny that the only time I had trouble with my reloads was using a single stage press. I measured and weighed every tenth charge, but I'm assuming a couple of under charged rounds made it through because I did have a couple of squibs in a six month period. Knock on wood, since switching, I haven't had a single issue.
