They are two different things! And the required game is a bit different! (although sharing some similarities).
I suggest you try both and find what is easiest for you - and then get good at that (get some results) and once you feel a bit more succesful, you try to go for the other one
Generally - in Eastern Europe (post--soviet) countries, clubs tend to be crazy loud and usually have a pretty crappy dynamic. If I where to go to georgia I would go for bars, or smaller dancebars or terraces!
