As a duel console owner, who loves both consoles just as much, this sort of conversation is pretty hard to quantify as frankly we all have our own personal tastes and preferences that are different to the next. What i like will be different to the next person, but neither of us are actually wrong
IMO ( don't hate me ) at this very moment i think the XB1 has better exclusive games. ( i said don't hate me please!!! LOL ) But then i love hack and slash games and RYSE fills that need very well on Xb1 side with nothing to compare that to yet on the PS4 side.
I also like my FPS shooters, and although Titanfall isn't the most deep game, it's stupendous hilarious bundles of fun and WORKS! You can't say that about the broken BF4 game. I also like driving games and Forza 5, although not as deep as Forza 4, is again actually supurb!
But the thing is this is just me. I love hack and slash, shooting and driving from time to time, others may not.
This will be an ever changing view to be honest because as soon as SONY release a new god of war game, or Uncharted, or The Order, my evaluation of "who has the best exclusives" will instantly change. On paper, SONY will have the vast majority of exclusives that for me and my tastes, will mean i prefer them. I love what ND, Santa Monica, Quantic Dream and That Game company, do, just as much as what Turn 10, Respawn, or Remedy do... but until we see games from all these developers, it will be hard to crown a winner just yet...
All i will say is, it's actually GOOD for SONY if MS DO come out will wonderful games, as strong competition drives the other to excel and not get complacent. Graphically for example, Santa Monica with god of war, are going to have their work cut out if they are going to beat RYSE.
This is a marathon everyone, we can't really crown a winner with any authority for a couple of years yet. I have to say though if i was a betting man.. i would put my money on SONY even though i prefer the XB1 games at the moment.
