Played on an XB1 but I own a PS4. You'll get fanboys in each camp but it is much of a muchness imo. Best thing is to go with the ones your mates have or folks you're likely to play with online.

​i had an Xbox one for a few years but made the switch a few months back. I switched mainly due to the lack of any decent exclusives Microsoft gave coming in 2017. Sony have so many good titles that I just have to play. The likes of Last of Us 2, Days Gone, Horizon Zero Dawn. You'll have Xbox fanboys but you can't hide the facts. The GPU in the PS4 is slightly better too so you'll find multiplatform games running at 1080p on PS4, but dropping to 900p or less on Xbox.

I've got both. The Xbox has a better controller and the Xbox live service is better than PSN, the PS4 is slightly better graphically and has a better user interface ( dashboard ). I use the Xbox more, but that is a personal preference, probably because it runs so quietly compared to the PS4 which is noisy for when I play at night and people are in bed.
There is a good deal from Game on here right now if you choose the Xbox.
If you game socially , go for the one your friends have.
