The Husqvarna you are asking about has a Commercial Large ring FN action as opposed to the actual Husqvarna action.
I would pick the FN action over the Zastava action every time. The FN action should have a FN style safety which I would pick over the trigger safety on the Zastava.
FN action will be the C ring type.
The Zastava action is probably just as durable as the FN but it's incorporates several cost cutting features including the general fit and finish. If you can find one of the old Whitworth Express Zastavas, it will be more on par with the Husqvarna / FN finish.
