The elderly wiseman (judging by his avatar) MrKahn asking for advice? I thought I'd never see this in my lifetime! Lol
I may not be the best to give advice ('cause I haven't got WiiU), but I'd say that I lean more on Batman and NG3, d21lewis sums it up pretty nicely of the different style of gameplay... If you want old skool with extra punishment arcade gameplay, go with NG3; if you want a modern openworld experience with a detective comic book anti-superhero setting, then I suggest Batman: Arkham City Armored Edition.
About Epic Mickey: Power of Two, I really can't say. Although I am a big fan of Disney's old properties, but this game is the least that appeal to me against the other 2 on your pickings.
Hope that helps, even though I'm not qualified... XD
