Okay internet help me decide: 2ds or new 3ds?

I'm revamping my holiday wishlist (to buy myself.) since the Pebble Time 2 won't be released until January, and I can't decide between a 2ds and the new 3ds [i]Super Mario 3D Land[/i] bundle. I don't really care about the 3D (it gives me headaches.) I just want to play my old ds games, and buy a few new ones like [i]Pokémon Moon[/i].

Do you have either of these systems?

Which one do you like better?

What's the better value?
