I've used a dizzying array of enlarger lenses in my life. All of them have their place. Most six element lenses are good enough if the elements are in alignment. I had a Componon-S once that wan't too good and was a little dusty inside. I took it apart to clean it and then I made sure the elements were seated correctly. Went from a dog to a gem. I don't think I've ever had an unusable six element lens. There are slight differences of course, but you'd have to put them side by side to really see them. No one could tell what was enlarged with what if the prints are hanging on the wall. And just because six element lenses are "technically" the best doesn't mean you won't like a simpler lens. I got an Elmar with my Focomat and never used it. One day I thought what the hay? and put it on. I just happened to be enlarging a portrait and it looked great. The grain wasn't that sharp, but overall the print was probably better than if I used a "technically" good lens since it fit the image. And the image looked really "old" like an old HCB print for example.
Years ago I put all the lenses I had to a test. The Orthoplanar won, but the Computar DL was right behind it, and so was the Minolta CE Rokkor. But I use the Rokkor the most these days because it works with my Focomat 1c. I'll change lenses on the Focomat though just for the heck of it. All the lenses I have are acceptable for what I do and I'd assume since I am picky they would be acceptable to anyone else too, aside from the "exceptionalists" that basically just make stuff up.
The list of lenses is pretty large. Rodagons, Componon-S, Computar DL, Minolta CE Rokkor, Fujinon EX, Leica Focotar 2, Durst Neonon, EL Nikkor, Meogon, Hoya/Yashica/Computar six element. Lots and lots of lenses to choose from and some can be had for peanuts.
