Mainly Schneider, I have 4 Componon S lenses, 80mm, 135mm, 150mm (Vivitar branded) and 300mm, a few plain Componon's 50mm, 105mm, 135mm, and a 75mm Comparon. Three Rodagon's 150mm, 210mm and a 240mm. All these German lenses are excellent performers.
I also have an 80mm Komuranon and 50mm & 80mm Minolta Rokkor's and some odd Japanese lenses, cheap ones sold under various names.
Yes it sounds like rather a lot but in fact only 3 were bought new, the Vivitar & Minolta's and they lasted 25-30 years they had very heavy use in a commercial darkroom and all now suffer from slight scratch marks from poor cleaning. The rest came mainly with second-hand enlargers, and then around 4-5 years ago I was visiting a friends pro-Lab for work and spotted an enlarger in a skip, when I asked if he had a spare 135mm lens he gave me two turrets full of Componon's off Durst roll-head printers, 6 or 7 lenses on each I gave all the spare Componon's away free here on APUG
I'd also go the Schneider - mine is a joy to work with; an older version so it doesn't have illuminated f-stops, but that's not really important to me. It's the optics that count, and both my lenses meet this criteria beautifully. (Rodenstock 50mm f2.8 illuminated f-stops, Schneider 105mm f 3.5)
