I have 5 Lee Pro Auto Disk and one Auto Drum that all work well with the powders I use.

I used the Auto Drum when I threw 2.3 grains of Clays or other powder drops that were less than the smallest auto disk cavity would drop reliably.

If using a very bulky powder like Trail Boss then drops of less than 4.0 grains may be a problem with the Pro Auto Disk
I use mostly Titegroup these days in 38/357 and Bullseye,Unique,2400 plus Trail Boss round out my 44cal powders.

The Lee Classic 4 hole turret press is a great inexpensive(subjective)reloading tool when paired with Lee 4 die sets,Lee Auto Disk,Lee Riser and Lee Safety Prime.

If you need to load more than 200-250 rounds per hour look elsewhere.
