Jupiter 8 - which one is better?

[no-X]

Does anybody know, which of these J8 versions is better?

1. the one from Zorki 4 - more common, later, but without any special mark
2. the one from Zorki 3 - more rare, older, marked by Π

I think that the later (not marked) is possibly not worse, just that the coating became so common, that the manufacturers marked it no more. Just like the old versions of Jupiter-9. But that's just my guess...
