I still love my WiiU. It's an underappreaciated little system and the gamepad is one of the most comfortabe controllers I've ever used.
I love the Switch too and I get why it's designed the way it is, but handheld play is so cramp inducing.
The wiiU has a great Library, similar to the Gamecube in that regard, but I feel like it will be less remembered for it because just about everything is getting enhanced ports/sequels now.
What really get's me is how almost every single Zelda game in playable on it, it really is a Zelda machine.
