It depends on how the gimmick works. Despite OOO being my favorite, I didn't really care for the Rider Medals. Not too hot on the Rider Switches either. The Memories and Lock Seeds were the best. The Wizard rings don't have too much functionality, but they certainly look very good.

If the sound gimmick has elements of the rider the gimmick is from as well as nods to the Rider it represents, it's cool.
