Which version of Shovel Knight should I get?

[garretslarrity]

So right now Shovel Knight is on sale on the eShop.  It is 33% off.  It usually costs $15, and is on sale for $10.  This deal ends on January 8.  It costs the same on both the Wii U and 3DS.  Since I have both systems, I was wondering, which version should I get?  Is there a difference?  Which feels better?  Does the Wii U version support the best controller ever made, the Pro Controller?

 

Edit:  Thanks to Jizz, I now know that the Wii U version does support the best controller ever made, the Pro Controller!
