Well... Asphalt 8 on the iPhone has pretty good motion steering.

Anyways, from what I've heard, the steering on the Tilt Pak was very good, the problems came in the form of the rumble feature requiring batteries (like with the old Rumble Pak) and the fact it couldn't be used as a regular Controller Pak (like the old Rumble Pak). Also, it was introduced late into the N64's life by a 3rd-party company, so it didn't really have marketing on its side.
