Been playing the PS4 version for a few hours, and I'm enjoying the hell out of the game. The hacking mechanics and the mission diversity have been good so far, and the story is interesting. I especially enjoy how differently various cars feel driving.
I know most of this thread has been devoted to comparing screen shots and videos, but that nonsensical cap aside, the game is performing like a champ. No frame drops to my eye and the clarity of the graphics and world are great. It's no Second Son, but I'm cutting Ubisoft some slack as the current gen versions probably held them back a bit.
It's early, but so far so good.
