Disregarding things getting blown up and sorceresses taking places over, I would honestly stick with Trabia Garden most likely. That Garden seemed to be more like a normal school; they didn't even host their own SeeD exams. I wouldn't work well as a mercenary or in an army I think, and I wouldn't get caught up with stuff like that at Trabia, I think. (Again, this is disregarding the missiles). It also has a small school feelings, which I like. The people there seem pretty nice. I didn't get to see their leadership in the game, but I'm imagining it was better than both Cid and Martine just because.
