PS4>WiiU>XO

Not interested in much on XO other than Sunset. Gonna get Smash for WiiU which counts as like 4 games for me because I love it's local MP that much. I'm gonna get Driveclub PS+ hopefully sometime this Fall (lol God I hate that I don't already), FC4, GTA5, Sleeping Dogs Definitive, SoM, Wolf Among Us, TWD Seasons 1 and 2, and LBP3 all for PS4 by Christmas.

Wii U
Smash, Bayonetta ,Captain Toad, Hyrule Warriors, Sonic Boom
Also that U craft game which looks eh right now

If you're talking specifically exclusives it's hard to pick. It all comes down to preference. Bayonetta 2 is a winner and so is Forza Horizon 2. Project Spark is a good game, but not for everyone, same can be said for Hyrule warrior.
SSO could be a hit or miss, probably closer to hit judging from the previews. Both MCC and Smash are going to be amazing.
I think the unsung hero for the X1 is Ori and the Blind Forest. I think the game will get stellar reviews.

Wii U because Smash Bros. That game alone is enough to 1up both PS4 and X1. On top of that Wii U already has a better Library than the Next-Gen Twins. So this holiday there really is no Competition. The Wii U still won't Dell though...

well like I said earlier halo mcc and sunset are interesting
halo will get great reviews(like smash)
then sunset and toad are interesting...

The X1 its not even close since Wii U doesn't have any 3rd party support.

If its exclusives, then wiiu, if you include multiplat, then x1

Depends on your preference for the games. Personally, I will have fun on both.

For exclusives? WiiU. FH2 is on 360 and Project Spark looks very bland and uninteresting. Not to mention it's very dependent on microtransactions which is a huge turnoff for me. Sunset Overdrive and MCC both look great but I don't think it quite matches Smash, Captain Toad, Hyrule Warriors, and Bayo2.

Ps4.
