>>328129232DS and OG 3DS is basically the same.
Why you should get a 2DS tho:
1. 3DS XL only stretches the screen. No increase in resolution. 2DS/3DS doesn't have stretched pixels.
2. It's comfortable as hell. Playing Monster Hunter with it has never been more comfortable. The design prevents having your fingers crumpled(?) uncomfortably. It's like holding a PS controller.
3. It's cheap.
4. It's durable as hell. No hinges is a plus too.
5. If you happen to brick it or break it, you can use it as a door stopper.
I have one, and I fucking love it.
