My preference is for well working ones...
More seriously, I have and use regularly several and like all of them. In my bag are a J-8, J-9, J-11, Industar 22, 26, and 61 l/d(some times these are marked l/z). I have two J-3 lenses and am still looking for one that is adjusted to focus correctly. When I get a good one it will likely be my main 50mm lens. For now it is the J-8.
I have had a good example of the J-12 but it wouldn't fit my Bessa R so I let it go. And am missing it.
Never owned an Orion; 28mm isn't a focal length I favor.
The I-22 is a somewhat under rated lens, I think. I have two--one rigid and one collapsible. The rigid I use on the Bessa and the collapsible mostly lives on my Zorki 3m.
Filters/hoods are mostly easy to find: The Jupiters 3, 8, 11, and 12all use 40.5mm (as does the I-26 and 61) filters and the J-9 uses 49mm filters/hoods.
The rigid I-22 uses a 33mm filter and those are tough to find. I got lucky and the lens I have came with the correct hood.
The I-22 collapsible uses a36 slip on or clamp on filters so I can use the same filters for that one as I use for my 9cm Elmar.
There are absolutely better (better built, better coatings, newer optical designs) lenses around but for me the FSU lenses work very well indeed for my needs.
