Wii on Dolphin VS Wii on Wii U

[Shonumi]

Dolphin all the way. Even if Dolphin had perfect compatibility and you stuck to 1x IR with no enhancements (making the Wii U and your PC running Dolphin more or less equal), Dolphin will let use just about any controller you want. Might sound silly to some, but that's a serious advantage in my book. Also, no need to swap discs (or resort to homebrew backup games) with Dolphin.
