I like the Ocarina, I do not like the harp in SS. If I am going to play an instrument, I want more control than just strumming up and down and playing scales. I know that you technically "learn" songs in the game, but it just didn't feel right, I was still just strumming and not controlling the notes. The Ocarina gives you that control, and the accountability of hitting the right notes, not just moving the wiimote in the correct way.
