mens, i were only in this 2 so idk about Ghent or Antwerpen
i kinda understand what you are saying but from tourist perspective Brugge is sooooo nice. I rly want to visit it again. Quite city, delicious food and beautiful architecture. I mean yes, there is no "teenager activities" (idk how u call them) but mens, at least they have a nice football stadium (i dont rly like football, cause im a hockey player, but still).
Yeah so next time i go to belgium i'll definitely visit Brugge again, but i'll try to visit Ghent or Antwerpen (or both of them)
