Keep in mind I've never actually used this before, so for all I know it could be terrible, but to me it seems like the best possible compromise between the M+K and a regular controller.
Pinpoint mouse accuracy, with a joystick instead of WASD. At the very least it seems like a neat idea.
The nunchuck part reminds me of the Wii's controller, which is also pretty good in my opinion.
