I played both, and people say the Wii U gamepad is useless, but I have to disagree with those people since, it just feels "more right" to play the original on the Wii U. I say let 3 be the Wii U's (not like it has too many other things going for it) and 4 is the Switch

I like the gamepad and IR controls of Pikmin 3, but I like being able to switch characters with the action menu instead of cycling through them in Pikmin 3 Deluxe.
