I never got to experience the Super Nintendo or SNES; back then I played Sega Genesis, and the controller was terrible, haha. But there are many opinions about the most comfortable controller these days, and I lean more towards Microsoft's design. When you relax your hand, it feels natural, and that's how Xbox controllers are designed.
