Stranger's wrath was very colorful but far from best graphics list gen, way far. It takes more than just color.
Halo Reach graphics: Kill a Brute and take a look at it. The Brutes textures are horrible and even Halo 3 had better graphics for the Brutes. Also, look at the big Monsters too. the huge monsters looked like HD versions of last gen graphics. Destruction? There really isnt any except for objects that actually explode.
Halo Reach isnt bad looking at all. I'd say that the graphics are pretty damn good and up there with some of the best on consoles but it would be close to last place when compared to the console big guns.
Graphics for consoles:
God of War 3
Heavy Rain, Alan Wake
Gears of War 2
Mass Effect 2
Uncharted Drakes Fortune
Gears of War 1
and then the rest would be subjective....unless i missed a few worth mentioning
