I have pokemon y. The exp share in this game actually gives the same boost to all of the pokemon in your team. So you can use that to grind your team. Of course, you can turn it off if you want a bit of a challenge

Well I don't a 3D ds so I cant get x or y but ill wanted y because you get cooler pokemon in it.

I have X. I dont personally think either game is better. But if you find somebody on gts or pss willing to trade you can obtain both ledgendaries along with some other pokemon you cant obtain in x ( or y) . Also I know where to get all the mega stones so if u want to find them all just ask me
