The Switch version for sure. It's got all the Switch hype.
Now the real question, which I'm sure we are all thinking, is which version will I get?? Dunno man - that 3D effect seems to fit this game perfectly on 3DS. But it looks nicer on Switch. And the Wii U version has those 3DS level, which I think sound cool. I'm probably just gonna get the original second-hand somewhere and be happy
