PlayStation handsdown. Grew up with this console series and love it. Also, the PS4 has more popular exclusive games compared to the Xbox One (and better Indies games).
Plus, PlayStation has SharePlay which is great for online friends that want to do local co-op or friends that want to watch each other play a game, take turns playing, without having to stream publicly. I can't believe Xbox doesn't have this feature. They have GameShare but it's not the same.
