I think it's close. 3DS has better Mario/Zelda games ... Link Between Worlds + OoT 3D > DS Zeldas, Mario 3D Land being a new Mario game is better than a port of Mario 64 DS (even though that's a great game), and NSMB2 > NSMB.
Third party wise the 3DS started strong but has started to fizzle a bit now. But it still has Monster Hunter, had Resident Evil, Street Fighter, etc.
But for me the 3DS needs an Advance Wars 3D before I can put it above my DS.
