What would have sold most? 3D World, Galaxy 3, or a Mario 64 successor?

Galaxy series was obviously helped hugely by the Wii Sports/Wii Fit crazes. 

I very much doubt the "soccer moms and senior citizens" were playing a core 3D platformer.

100 million userbase helped all the Mario games. 

Mario 3D World would've sold 10 million easy on the Wii, probably more actually due to its multiplayer gameplay.
