What's the best looking PS4 exclusive game?

It's too difficult for me to decide since both are different genre.

Probably Killzone is slightly better but that's because it's a linear corridor shooter.

Infamous is a open world with plenty happening on screen. Both are impressive.

Infamous...I was quite underwhelmed by Killzone

I havent played Knack or Infamous, but i do own Killzone ShadowFall. Till this day, im very impressed with the visuals. One of my favorite displays of the visual flare is when you get stunned (in multiplayer), all those particle effects look awesome. Its probably the only game where i look forward to being stunned lol. Infamous looks great from what iv seen, and i actually think Knack looks great for what it is.
