If you already own PC, PS3, or 360, then neither (that's why I voted for "Tank"). But if this is your only opportunity to play them, and you don't mind that they're flawed ports, then either one will do. Just watch their respective trailers and go with whichever one suits your mood.
Honestly, though, the best games for the Wii U are Mario, N-Land, and Nano Assault. I'd even recommend Ninja Gaiden since it's such an improvement over the other versions.
