SNES. It just had way more games that I enjoyed, such as:

Super Metroid
Super Mario RPG
Chrono Trigger
The Legend of Zelda: A Link to the Past
Final Fantasy IV and VI
Illusion of Gaia
Super Mario Kart
F-Zero
Super Mario World
Sword of Mana

That's all I can think of off the top of my head, but I know there are many more.
