To me, everything RCBS is annoying. I am a hater.
Every little adjustment to the dies require tools. Want to screw the die a little bit into or out of the press? You'll need tools to loosen the lock ring. Want to adjust bullet seating depth? You'll need tools to loosen the jam nut on the seater stem. All the common operations are made three times as time-consuming by the need for tools.
The hand priming tool requires complete disassembly to change the shell holder. You can't load 100 primers into the tray and do 50 .45 Colts and 50 .41 Magnums, because you will have to completely take the tool down to switch between those two.
Something about the presses suggests to me they are overbuilt because that was easier than putting some proper engineering into them. Just throw some more cast steel in there, it will be fine.
