Xbox doesn't really have exclusives anymore cos they're all on PC now, so only some older games, which honestly aren't all that good, like Halo: MCC and Halo 5 (which is still on PC, just not the full game).
If you seriously want a console for exclusives... no joke, WiiU. All it really has is just exclusives. Most of them are good, but recent releases have been bad, not to mention lacking. Just don't buy anything that released in 2016.
PS4 has some decent exclusives. Funny thing is that it's all I have on my PS4: Uncharted Collection and Uncharted 4, Ratchet and Clank (highly recommended) and Bloodborne if you like Dark Souls and getting stuck on the same boss for hours, lol.
I've not played Infamous and Killzone, but they are okay from what I hear. Until Dawn is a decent horror title... and I'm getting De Ja Vu from listing all these exclusives. There is one game which I won't mention, because some people get very... 'defensive' over it, it's a marmite game IMO. Either love it or hate it.
