Here's what you are missing
Continuous vs Batch processing
As you already know, a turret press is just a single-stage press (the bottom end, where the ram holds but one cartridge case at a time) that holds more than just one die ready. It can still only use one die at a time. But the ease of swapping one die for another enables the user to process in batch mode or in continuous mode at will.
Batch processing: you are probably familiar with. Whether your batch size is 20, 50 or 100, the operations are the same. (For pistol) Size/deprime and prime 50 rounds, then switch dies and bell and charge 50 rounds. Inspect the charges in a batch and switch dies. Seat and crimp 50 rounds. Batch is done. Move on to the next batch.
You have inserted and removed each case a number of times. This handling takes time
Continuous processing: Put the empty case in the press and do all the operations (size/deprime, bell/charge, seat/crimp) and remove the finished cartridge only when all the steps are done.
Because continuous processing eliminates a lot of handling the cases (at least three insertion-removal cycles) it saves a lot of time.
While the Lee turret press only holds 4 dies, swapping turrets can be done in 15 seconds without tools. The Lee also automatically rotates the turret (if you want it to).
