It's funny you ask this, as when I purchased my first Rodenstock, I thought the aperture ring was broken since there were no clicks like the Schneider's have.
As to what I prefer most, it's tough to say. I feel that as you point out, the Rodenstock solution may give a bit more fine control but have not way of really knowing this since on the tech camera there is not way to get your aperture setting. I used to think that by putting the shutter speed on a copal between two of the marks, you could get a shutter speed between two of the fixed settings, i.e. 1/30 and 1/60 to get 1/45th but that doesn't work either.
The Rodenstock solution is easier to move and not realize it, however the Schneider's bury the aperture ring down so deep, it's hard to get to it, (at least for me) on the SK35 and SK43. SK35 especially.
I guess overall I still like the hard click.
