From a pure conceptual perspective, which is the better "Gimmick controller", Wii U Gamepad, or Joy-Con?

WiiU game pad is better, conceptually. In reality though, it hit the market several years too late. By the time if came out if felt like ancient tech, going up against Ipads and the like. Joycons are just a hybrid wiimote/normal controller.
