There is not much difference between the Rodagon and the Componon-S. Both are good lenses and when bought used condition (internal haze, separation) is probably more important than the name.
I have a couple of Rodagon lenses, kept them over the Componon-S lenses, no ral difference in actual use for B&W, but the Schneiders wouldn't allow my lens turret to rotate. I have the same problem with 50m El Nikkors. I could have used different mounting plates, but the 50mm wouldn't focus when I tried it on one. The 80mm Comp-S kept banging the rear cone even with the proper plate. If you could use a 25mm mount lens, I would recommend a Wollensak 90mm for your medium format, it was designed for 6x9and does a great job running a 6x6 neg up to 16x20 on my D-6 base, excellent corner to corner coverage, no fall-off.
I once pondered on the thought of getting those wollenstock and kodak ektar enlarger lenses, but costs were prohibitive. The 25mm to 29mm adapters arent cheap, and these older lenses dont go for cheap either, and dont usually start low if buying auction. The el nikkors, rodagons, and compnons can be had usually the same price or cheaper in good used condition.
Finally a subject that everybody seems to agree on!
If you get a second lens that is from the same series as the one you already have, the operation (click stops, aperture setting illumination and direction) will be something you are already familiar with.

Yep, this is what I'm thinking. I'm now looking for an 80mm Componon-S to come up for sale. I see there is an older 5.6 version as well. I would like to find the newer f/4 version as it's operation is the same as my 100mm.

my Apo Rodagon lens is even better, and nearly in the league of my Apo Nikkors (which are slower
and not avail in short focal lengths, so not directly applicable to the question). I do both color and
black and white work using film sizes all the way from 35mm to 8x10, and have probably used over
twenty distinct enlarging lenses. But any of these lenses would be better than the old Componons
(vs Componon S). I have never owned an Apo Componon because they aren't made in the focal
lengths I prefer.

When I bought a mint 50 current model componon-s, I found the results from an old Durst Neonon I won at the same time on ebay much nicer. Perhaps a bit more contrast... but the prints seemed to have more substance and the best prints from the Neonon looked better than the best from the Componon-S no matter how hard I tried. Hard to define, but it was immediately obvious and I did not use the Componon S again.
I ended up with a Nikkor 63 2.8 due to vignetting issues with 50mm lenses on my 10x8 enlarger and found this produced prints identical to the Neonon (mine is made by Pentax) but free of vignetting at wider apertures (an enlarger issue).
I also find that my 105 rodagon 5.6 distinctly superior to my 80 f4 rodagon. Both are late models in the plastic barrels. The 80mm cannot match at any aperture what the 105 will do at f6.7-8. There is more sparkle and more edge to the grain from the longer lens. You'd never think anything was wrong using the 80mm only, but next to the 105 you DO see differences in the print.
My 150 Rodagon to my 135 Componon S produce indistinguishable prints really....
... so I guess in some cases one is superior to the other, but as for a general rule, forget it!
I have APO-Rodagons, APO-Componons, and Rodagaon-Gs. They are pretty much the same -excellent. The only caution I would have is that both Rodenstock and Schneider have made (or do make) less expensive brands than the Rodagons and Componon-S's. These are generally inferior in some ways.
