SuperNES and NES Classic controllers can be used on either system, and since they can dual boot either is perhaps the same in the end. It's just that the SuperNES classic comes with two controllers and they have longer cords. It also cost $20 more retail. They are turning out to be great systems. I enjoy it a lot more than I thought I would. The game play is quite authentic to original, no screen tearing and sounds are right on. The save states and rewind feature are very fun, and allow you to enjoy games you probably have already played through in the past more casually if you are just looking to focus on fun.
