Better at what? Being big and clunky? Oh man, can't wait to play Star Fox SNES on the go... except that I could just play 64 3D, a much better game, on 3DS.
Oh but wait, SNES has Chrono Trigger and Final Fantasy... so does 3DS, thanks to backwards compatibility with DS games.
Super Mario World & Yoshi's Island? NSMB, NSMB2, 3D Land, Land 1 & 2, Wario Land, SM64DS, SMB, Lost Levels, SMB3 soon...
Super Mario RPG? Mario & Luigi: Partners In Time / Bowser's Inside Story, Paper Mario: Sticker Star...
A Link to the Past? Is that the only Zelda game on SNES? 3DS already has Ocarina of Time 3D, Link's Awakening, Zelda 1 & 2, Phantom Hourglass, Spirit Tracks, plus Four Swords Anniversary Edition and The Minish Cap if you were quick to pick one up.
Anything SNES can do, 3DS can do better.
