I think it's safe to say that God of War 4 looks better. That said, this looks to have Uncharted 4 beat which is an amazing accomplishment.
However, is it really that surprising considering Killzone 2 and Killzone 3 were the best looking games on the PS3?
Sucker Punch has been improving with every game. Infamous 2 was a huge improvement over the first somewhat ugly looking Infamous game. And Second Son was easily the best looking next gen game when it came out. I have no doubt that they will improve their engine even more with their next IP.
And of course let's not forget the best looking racer of all time.
Sony has cultivated some of the best talent in the industry, and i hope they stop closing down studios and invest some more because I really dont want to play trashy looking games like Dishonored, Fallout, and downgraded shit like Witcher 3 and Watchdogs.
