    I'm not sure if it's possible to generalise very well about the Jupiter lenses. As far as I know, the Industar-xx lenses are always approximately 50mm (and I think always or nearly always Tessar types), and almost everything else---longer, wider, faster---is a Jupiter. Some are really nice lenses---the 35mm J-12, a copy of the Biogon, particularly so---but as with most things Soviet, quality control varies, and some of the higher-spec Jupiter lenses have a fairly extreme reputation for variation.

    The Jupiter 8 lens on my Zorki 4 is much better than the Cintagon lens on my Argus C44. So, if I want to use a cheap fun, kitch camera I pick up the Zorki. The Argus C44 sits on the shelf since getting the Zorki.

    The Cintagon, if I recall correctly, is a triplet.

    Industars were Tessars. The collapsible LTM Industar were not exactly Elmar copies- only the mount and the barrel was copied. The lens was Tessar (though Elmar were also Tessar copies), but the diaphragm in Industar lenses were located the same place as they were in Tessar: between the middle and last groups. In the Elmar 5cm (though not in the Elmar 90 or 135 -mm), the diaphragm is right behind the first group.

    Jupiter were mostly Sonnars- 6 or 7 elements. The J-12 though was Biogon.

    Quality-wise, it's hard to see which does better when stopped down at f/8. Or when looking at photos at usual print sizes or on screen.

    Tessar Industar tend to be better generally- when manufacturing quality is concerned. Focus issues arising from calibration of lens barrel or camera aren't as serious as with the more complicated wide-aperture Jupiter. Some of the later Industar, like the I-61L/D, give more contrast.
