In my opinion, the Wii U's biggest issue was the gamepad. It was far too costly and resulted in a console that couldn't get price cuts despite desperately needing them. While the Wii U has some great games, I feel like Nintendo had internally realized their failure and focused much of their efforts on the Switch long before the Wii U had run its course. As a result, the Switch ended up having far more resources put into it than the Wii U did.
