I bought OR because who doesn´t love Groudon?
But AS would be better becuase Kyogre is stronger than Groudon and I heard many good critic about Team Aqua in AS
But I think you should buy 3DS Smash Bros becuase it´s the most popular Multiplayer game here and it´s played almost everyday.You just need the people´s FC.
And don´t buy Tomodachi Life it got boring really quick for me and many others.
