I've never used an RZ67 but maybe the removal of the exposed spool is easier on its back? The Rolleiflex can be fiddly and can allow for a bit of unwinding of the film while oyu try to grab an edge and hold the spool knob out and such at the same time.
One thing, I don't have to pull as much paper out to get it on the take up reel. I just watched a video of a guy load a Rollei and he wound less paper onto the take up reel than I did. I wound until I saw the indicator arrow on the paper, and then closed the lid.
