There are variations from sample to sample, from model to model and sometimes you prefer one brand in one focal length and another in another.
FWIW I find the top Nikon lenses comparable to the late model rodagons. My most used lenses are:
135 Componon-s / 150 Rodagon
I certainly prefer 50mm Rodagons to Schneider Componon-S lenses. Its something to do with the tonality/contrast of the latter I don't like as much but its entirely personal.
One brand consistently better than the other? Not to my eyes.
