I'm inclined to give it to XBOne. Even when we only consider exclusives*, I'd still give it to XBOne. (Like it or not, Halo:MCC is effectively 4 and a half games plus online for all of them is a fantastic deal for $60, and I'd purchase an XBone for that if I had more cash to blow. I'd buy an XBOne for Halo:MCC.)
*Game on XBOne, but not on Wii U
But, screw that! Bayonetta 2 hype train, here we come! (Not as hyped for Smash, but I'm sure as hell hyped for Captain Toad, HyWa and Bayo2.)

I WON A BET AGAINST AZUREN! WOOOOOOOOOOAAAAAAAAHHHHHHHHHHHHHHHHHHH
:3
