Local guy here.
I would recommend Serbia. The women are more beautiful than in Croatia (not a big difference, though). And you get more bang for buck in terms of food, drinks and accommodation. I'm comparing Belgrade and Zagreb, of course.
I've never been to Slovenia so I cannot comment on this.
Bosnian girls are not as fine looking as Serbian girls, so why bother?
The same goes for Macedonia.
