From my use, it's a very nice lens given a bad rap mainly because it
was sold at a low price as a "novice lens". Who wants that when you can
buy a pro lens? :P

It's multicoated, comes in a modern, reliable shutter and is
small/lightweight. It actually folds up in my super graphic.

Given most LF lenses are used around f22, the wide open edge performance
isn't an issue for most people. I've actually done some portraits with
mine on 4X5 at f11 and they look great. The only disadvantage I see with
this lens is the smaller image circle compared to the much
Larger/heavier/more expensive plasmat types. If I had to choose this
over some vintage lens that has questionable coatings and flaky/ancient
shutter, I would get this one in a heartbeat.
