I have heard almost nothing good about the Wii U version. It looks worse, plays worse, and is all around crappier than the Wii version. The flying controls are apparently imprecise and jarring on the Wii U version, reflecting that nobody on the development team wanted to actually try making a Wii U version to begin with. If the Wii version had come out solo, the game would probably be sitting at a comfortable 8/10 or so average. Instead the Wii U and 3DS versions of the game were thrashed for being essentially port trash, and the Wii version kind of gets forgotten in between.
Essentially, just play the Wii version.
Then again, you seem to have some weird attraction to bad games, so maybe the Wii U version will be right up your alley. (slight trololo)
