As for now the X-Box One has more / stronger exclusive games:
Crimson Dragon,
Killer Instinct,
Project Spark,
Halo 5,
D4,
Titanfall,
Quantum Break,
Forza 5,
Ryse - Son of Rome,
Dead Rising 3
VS the PS4's:
Killzone,
Infamous - Second Son,
The Order 1886,
Drive Club,
Knack,
Deep Down (but I wouldn't even count that one at this point, because Capcom tends to lie to the customers big time)
X-Box One has the better exclusive titles IMO, as for now. But having better exclusive titles as for now does not outshine all of the heavy, heavy, heavy disadvantages the X-Box One has, because of it's bad policy, anti-consumer practices and most importantly attitude.
