In some ways the 3DS version was better but in other ways the Wii U version was better, and I liked them both. Although ironically, i find myself playing the console version if I want a quick fix because the levels are shorter and I only play the portable version if I'm looking to play a longer game because many of the levels do go on too long.

I preferred the Sky Road levels in 3DS where they became the casino level but I also loved the Frozen Factory level on the Wii U version for the same reason. I really liked the Silent Forest on 3DS better than Wii U but thought Desert Ruins was better on Wii U than it's counterpart. they have largely the same content, it's just distributed differently and certain level elements are emphasized more on 3DS
