I got a New 3DS when I graduated last May, but mostly to upgrade from a regular to an XL 3DS. The new bells and whistles of the N3DS are few and far between. You do get the C-stick pad thing that allows you to control camera, which is nice for games that recognize it. There's built in amiibo functionality, but you might as well just get the cheaper $30 extension if you care that much about HHD or Smash 3DS amiibo support. The camera tracking does make 3D much better most of the time (when it fails to recognize your face though, it gets pretty bad for a few seconds), but at this point I don't bother with 3D. You also will need a new micro SD card, and a screwdriver because oh god is putting that thing in a pain.
If you haven't played Xenoblade Chronicles, that's a major plus. Xenoblade Chronicles is a great game, and while the Wii version is probably the definitive version by a noticeable margin, if you're not wanting to spend money for the Wii version then the N3DS is the way to go.
Overall, if you the cards line up right and there's lots of little bells and whistles you need (e.g. you need amiibo support, you want Xenoblade, you want better 3D), then it might be worth it. But otherwise, eh, there's not much reason to recommend it over the regular 3DS.
