As I heard it's like this... If your primary goal is alpinism as top sport and you really want to climb in mountains very actively at highest level and if official titles are important to you then go to Kranj.
If good company is important to you and if there's something else in the world for you besides alpinism go to freeapproved. They are pretty cool company, I met them parking in crags and we kinda laughed at them.
Anyway check both websites a bit and go to presentation meetings. Costs you nothing and you'll decide easier.
Good luck!
