I hear 2ds are pretty decent if you don;t need to go anywhere, they play well and it is impossible to break the hinge ((since they don;t have one)). It has less chance of wearing out is basically what I am saying here lol. But up to you dude. I don;t tell people how to spend their money.
I have a 2DS and it's not bad. My only complaint is that it doesn't fit in a pocket otherwise I love it. As for ORAS, I still haven't played it myself.
