Metal Gear Solid 4 ot Killzone 2 - Which has better graphics?

[Scoobes]

Technicaly, I'd say Killzone 2 has the better effects, lighting etc. However, I prefer the artistry in MGS4. I remember comparison vids showing they'd reduced some of the effects from previous trailers of MGS4 but the artists added a few things and it still looks amazing.
