I have used and own these lenses from the manufacturers that you mentioned: Rodenstock Rodagon 80 and 50 and Schneider Companon 80 and 135. They are excellent lenses.
My all time favorite in a 150 mm lens is the Nikon El Nikor. A fairly pricey beast but I found one used. In my experience, it creates a difference that is discernible from the others. It is the only lens that I use today.
