F-Zero, hands down. Even though I've never played a game in either franchise, Diddy Kong Racing overall is just too similar to Mario Kart to justify its existence over F-Zero. There's nothing on the Wii U that can compete with F-Zero, and it would really add diversity to its library.
Plus, can you just imagine that kind of game in glorious HD 60fps? We got a taste of it in MK8 and I want more tbh.
