As much as I love The Last of Us and its graphic, I think God of War 3, Ascension and especially Uncharted 2 and Uncharted 3 have the prettier graphics.
The art design in The Last of Us is great, but less spectacular than those (maybe it's just the setting being less inviting for beautiful vistas) and it also lacks the spectacular set pieces of the other games (which makes sense from a setting, plot and gameplay prospective, but we're talking about graphics here).
I also think TLou is the only one with some minor graphical hiccups, as the pop-ins in the car and horse scenes.
So if I had to pick one as graphics king, it'd be Uncharted 3.
