PS2, PS1, Gamecube and N64 had some absolute gems but in terms of sheer volume, quality, variety and it's SNES by miles.|
Link to the Past, Super Mario World, Yoshi's Island, Super Metroid, DKC, DKC2, Megaman X, Kirby SuperStar, Streetfighter 2: Turbo, Chrono Trigger, Final Fantasy VI... the list goes on and on.
Also, aesthetically and functionally, the SNES had the best 2D controller of all videogame history, hands down. An actual piece of art.
