I don't have the 105 nikkor but I do have the 100/5.6 Componon-s and find it one of my sharpest enlerging lenses (I have a few enlarging lenses). I'm not sure that my APO-Rodagon-N 80/4 is any sharper than the Schneider 100/5.6 Componon-s although I haven't compared them directly. I have several Nikkors, 50/2.8, 63/2.8, a couple of 75/4's and all are extremely sharp so I would expect the longer lenses to be extremely good too. I don't think either will dissapoint.
Although these are tests as taking lenses in a macro setting I think they are quite telling. There's a test of the Nikkor here:
And a few other enlarging lenses here:
