All metal has play in it (you can bend it), so a turret has that plus more play given all the moving parts.
If your willing to ignore this then it doesn't matter what you pick.
I know my Lyman turret press had some slop in it, but the ammo I loaded on it seemed reasonably accurate. I'd expect Redding to do a better job on their turret press.
The thing is, the majority of the precision is in the dies, or not. So long as each stroke of the press puts the case the same depth in whatever die you are using, to a large degree the press has done it's job.
