I really liked the R. However, I sold it.
I have an L and find it to be adequate. Constructed of cheap materials, and I doubt it would stand up to heavy use.
I also have the Rollei 35 RF (R2 clone). It's a very nice camera. Being a Cosina Voigtlander, of course the rangefinder is slightly out vertically. Man, I wish they would put some R&D into that part of the camera and fix once and for all.
I don't have any of the newer cameras, as I find them to be unattractive.
