Zorki, which one to choose ?

[GeorgesGiralt]

Hi folks !
Suppose you've to choose between a Zorki-3 and a Zorki-3M. Both same price, with same Industar lens, and same condition.
Which one would you pick up ? And for what reason ?
Thanks for your help !

To collect: the 3, because it looks far nicer.

To use: the 3M, because it has a much more reliable slow-speed escapement. The escapement in the 3 turned out to be unreliable so the design was changed and the 3M was created.

The 3 really is a lot prettier, though.

Form or function?

(I say get a Zorki 3 for show and a Zorki 3C or 4 to use...)
