The new RCBS Rockchucker has an abysmal primer catcher that just as likely dumps them on the floor.
Hornady's Lock-N-Load Classic press also uses a plastic primer catcher tray, although I can't rate it. The Lock-N-Load die bushings are quick, but you need one for each die. I have over 100 die sets - so that means I still have to change them out or invest too much.
The RCBS and Hornady powder measures are nearly identical, they both work the same. The RCBS case activated powder drop mechanism on the Pro 200 Auto Progressive press is licensed from Hornady - it's the same thing. I found electronic scales too slow, and prone to inaccuracies if not maintained perfectly level. They are sensitive to air currents. The old balance beam scales are fairly bullet proof.
I have both the RCBS Pro 200 Progressive and a Hornady Lock-N-Load Progressive. The Hornady is a early model, it was so prone to breakage and primer jams, that I discontinued using it. They have since redesigned the primer feed. Nice shell plates though, better than the RCBS.
The RCBS Pro 2000 uses the CCI Strip Primers, or any brand can be loaded into the strips. Their shell plates are finicky though, some care is needed to prevent powder from being ejected from cases full to the shoulder when advancing the plate. RCBS provided a lighter plate indexing spring to stop the detent ball from snapping home and knocking powder out of the cases.
I switched to a Redding T-7 Turret Press for load development (still had to modify the ram so spent primers wouldn't drop on the floor), and use the RCBS Pro 2000 for volume runs. Some say the Forster CO-AX press is the best, no shell holders needed. Dies snap in and out on the lock ring. The behemoth of presses is Richard Corbin's Walnut Hill Press for bullet swaging and reloading, at $435

I use all brands of dies - RCBS, Redding, Forster, Hornady, Lee.
Why not go to each manufacturer's web site and download a manual for the various products, that might help with a decision.
