The 3DS version is the exact same game, lol.

Only thing it lacks is full network online, which is fine, because everyone just uses Brachy weapons on Wii U anyway.

The 3DS looks better, in my opinion. despite the fact that Wii U's version is clearer edge-wise, the game was originally designed to be displayed on the 3DS system, so the blurred textures and flat backgrounds are not nearly as apparent as they are in HD on the Wii U. Don't let blown-up screenshots or youtube videos fool you, the game looks amazing when running on 3DS's screen, even on XL.

However, a major imrovement that is made on the Wii U version is the control options. While the 3DS version is not hard to control by any stretch of the imagination, the dual analog control and more ergonomic design of the Wii U pro controller is much better than the 3DS control layout.

So basically, if not having network mode is a dealbreaker, I'd say the 3DS version is not for you. Other than that, it's the exact same, in fact the original format of the game, and I highly recommend it.
