I sometimes did these battle facilities, and boy I suck badly at them because the opponents always find a way to get sneaky or counter me. It's all because I'm not good at competitive battling, but I still do the Battle Maison in the 6th Gen to save up BP for items, or in OR/AS the Move Tutors.
5th Gen's Battle Subway was extremely difficult to me to be honest, and same with the Pt/HG/SS Battle Frontier. Never bothered with Emerald's one sadly, because my brother was hogging the game and wouldn't let me play it.
