The amount of ammo you need and the amount of time you want to spend on reloading should be the main criteria in deciding whether a turret press is adequate for you. I don't know about .223s because they need case lube and lube removal but estimate about 1 hour to load 250 rounds of .357 on a good, reliable progressive press like the Dillon. That is not a hurried pace, and time includes setup and cleanup. After getting to the point where I wanted to shoot more than 100 rounds per week, I bought a progressive. The routine that fits my busy schedule best is to do 500 at a time in one caliber. That keeps me in ammo for at least a few weeks, and often longer.
Contrast that with my output on a single stage where it took about an hour and a half to do 100 rounds of 45acp. I'd spend more time loading than shooting. That was just too tedious.
Some like the turret press, but I regard them as curiosities that date from the era before progressives were as cheaply available as they are today. I believe that shooters with ammo needs consistent with the normal output of a turret. Speed gained in using a turret is dependent on the forethought and efficiency of the operator, so if you get one, make sure you think the process through or you'll find yourself loading no faster than with a single stage.
If you get a Dillon and want to alternate between .223 and .357, it will be fast to change calibers because they both use the same size primer. If primer size was different, then it would take significantly longer to switch.
Finally, beware of claims about cartridge per hour productivity. If it doesn't include all of the time you spend, from setup to cleanup, then you can easily be misled. The companies that make progressives have a very optimistic rates that cannot possibly include setup, cleanup, periodically checking powder weights, and other things that take time. Certain true fanatics claim they their turret is as fast as the claims made by the progressive press makers-- shades of John Henry.
