Well the U is 100 dollars cheaper and fully hacked at this point. If 100 bucks isn't a big deal and you don't really care about any other Wii U games, I would probably get the Switch. It's portable and might have some more good games in the future.I don't have a U and will need to buy either the U or Switch to play this. So I am conflicted.
I'm playing on the Wii U.
