I haven't spoken about sales, I especially said ONLY exclusive wise, so I dunno why you still come up with that.
Plus I said in /my/ opinion and I never said it was competing in ANY other regard. Don't waste your time debatting other peoples opinion.
But if you like: Hyrule Warriors, Zelda U, The Wonderul 101, Bayonetta 2, Zelda, XCX, SSBU, Splatoon, MK8, Project Zero V, Star Fox Zero, Super Mario Maker.
You won't find enough exclusives on the other two /for me/.
Believe it or not: I'm not alone (which doesn't change the fact that ALL three consoles fanboys are talking/writing stuid stuff), though this is the reason for most Wii U fanboy bullshit talk.
Though most people I see don't say Wii U's a beast, but simply not as bad as PS4 and Xbox One fanboys say. That's true, Bayonetta 2 looks great, if you hear Wii U fanboys: PS4 Level (because obvious reason they dream of), if you hear others: SNES Level (because Wii U is shit).
The truth is somwhere in between. But as long as one consoles fanboys don't shut up, don't waste your time making the other two's. It won't work. As long as there's one PS4 fanboy who say Wii U is shit, there's always that one Wii U fanboy who says it easily competes. It's the endless circle of fanboys, their essence of life.
Conclusion... You could replace GC with Wii U in this pic.
