It is hard to compare the two. I have played both and think they are very much different. The world of Gears of War 2 is destroyed from war. The world of of Metal Gear Solid 4 is not. That makes it hard to compare the two.
Metal Gear Solid 4 - Amazing Graphics but mainly focused on characters and not much else. Textures are not that amazing. Characters are Very Very amazing.
Gears of War 2 - Amazing Graphics Focused on all sides, Characters, Surfaces, Textures, environments, atmosphere, particles, etc. And even though they made so much of an effort on all of the graphics in Gears of War 2, the Characters are still up with Metal Gear Solid 4 somehow! Metal Gear Solid 4 cannot compare with anything apart from Characters.
I do think Gears of War 2 has the best graphics for this Generation (So Far)
Its Characters, Environments, Textures, Surfaces and Particle Effects are just The best!
