I spent a long time with my two primary medium format cameras being a Rolleicord Va(fitted with a Rick Oleson screen-way back in 2007) and a Rolleiflex Automat. I think my Automat I finally decided was a Model 3. Both of these cameras have coated f/3.5 Xenars(my Rolleiflex has a Compur-Rapid shutter, the Rolleicord a Synchro-Compur).
15+ years later, I can't tell you what film came from which camera unless I have a specific recollection of using one. I shot almost exclusively transparency film then, primarily Provia 100F and Velvia 100F(I was in college and got great deals on some short dated and recently expired 20 roll boxes of both) and my transparencies certainly speak for themselves in image quality. I still have ones that wow me even so many years later.
It's true that the Rolleiflex has a lot more to go wrong than the Rolleicord. I actually bought my Automat advertised non-working(would not start frame counter) on Ebay and dove in head-first. I dug through what information I could find on the internet, learned all I could about how things like the Automat system worked and how to adjust it, and ended up setting it up to work perfectly. It still gives better frame spacing than any of my Hasselblad 120 backs...
Both cameras are very useable, but there's just something about the Rolleiflex that I love. It's very satisfying to load film, crank it, and hear the "clunk" that tells me the counter is starting. I also much prefer the ergonomics. With the Rolleiflex, I can focus, set the exposure, and shoot with all the controls just falling right under my hands when I "cup" the camera in them. I only have to take my right hand off the camera to advance the film. On the Rolleicord, I'm constantly moving my hands around to adjust the exposure, then cock the shutter and release it. Everything about every Rolleiflex I've ever used just feels so much more refined than any Rolleicord I've ever handled. Both are still nicer than the Yashica 124, which gives you the Rolleiflex ergonomics but not the fit/finish...
