As a big fan of motion controls,
Metroid Prime 3. Still the best FPS controls I've ever had the pleasure to experience all these years later.
Red Steel 2 and Skyward Sword. The ability to switch from excellent IR shooting controls to near 1:1 sword-fighting controls on the fly is still very impressive, and I love pretty much everything about Skyward Sword's controls with the exception of the swimming.
Every Smash game that uses the Gamecube controller. Melee, Brawl, Wii U, and Ultimate.
Exitebots nailed motion controlled steering better than any other racing game, and as a result is the most fun to control by tilting the controller like a steering wheel. None of the Mario Kart games that use motion controls do it as well as Exitebots
Pretty much every Mario game except for Sunshine, where the camera made some levels unplayable.
Wii Sports and Wii Sports Resort. The epitome of fun controls.
