Even from their reveals, I found Xbone to have the better launch library of the two. Nothing has changed; Killzone and Infamous do nothing for me, and I played Knack but found it to be horrendous. Dead Rising 3 and PVZ at least look like a bit of fun. I've only managed to play Titanfall on the Xbone, not bad but not for me.
Overall, I'm very happy with my Wii U.
