When it comes to older and particularly "user" grade Rolleiflexes, the overall condition of the camera and the lenses have a FAR more impact on results than the comparison of the different types of lenses. Many of these older/user cameras have front standards a little out of whack, or backs that do not close as tightly as they should, or focusing screens that are not altogether flat or straight, etc. that can make one lens seem to perform better than another. I have a feeling a large majority of these "I had this one and that one and that one was better..." comparisons are more the individual cameras than the actual indication of which lens is better.
