XY didn't really have much variety in endgame where level didn't matter (I was already too overleveled for the chateau and Looker quest so I just swept through it), besides from the Battle Maison which I found really boring since it was just lifeless fights with the same general Pokemon over and over. The bosses twenty and fifty fights in was cool, but it just got unfair by the end and I just found the whole ordeal repetitive.

Anyway, I was just wondering how the Battle Frontier from Emerald, and potentially ORAS, compares? I've heard good things about it and it seems more fun.
