I play on both systems due to same situation with friends. I'm a bit more biased to x1 since I'm trying to get higher achievement score. Sony has paid a ton for exclusives for every triple AAA title that's multi-platform. X1, however, has more unique exclusive games coming out this fall and into next year whereas Sony's exclusives while announced are not expected to hit until later next year into 2017. For Destiny : Ps4 pros: I can say the party chat system and messaging is far superior to X1. MS really dropped the ball on this one. The one caveat now is that they are planning a major update this fall that is suppose to fix it all in lieu of Win10. Fireteam capabilities. Bungie for some reason gave amazing options to bring whole fireteam into another fireteam, privacy settings all within the game to PS4. X1 it is so clunky and you have to go outside game to friends list to make your invites to fireteam private. Exclusivity in exotics and strikes. To be honest only one strike is enjoyable. All Year one exclusives expire in Sept. Not sure what TTK has exclusively. Graphically I see PS4 runs smoother but the colors seem a little more washed out compared to x1. I have to constantly readjust settings on TV. Cons: Ps4 network is constantly going down and have random updates. Network being down is obviously a big one. I don't feel the community engagement like I do on X1, although I'm more biased as I have established a community from 360 days. Competitive play is weaker compared to X1. Controller is not made for long usage. Thumbsticks I replaced with X1 thumbsticks as did many of my friends. X1: Pro Stronger community. Stronger network (none are perfect). Competitive play more intense. Achievement Score. Controller rocks (elite controller is on the way!) Cons : see above. Pm if needed.
