Uh.......everything looks better than CoD's engine. CoD has infamously bad graphics and the physics/visual effects of the engine are next to none.

Personally i prefer Unreal or Frost engine. Although to be completely honest games that look good and games that play good are usually never the same.
I think the ONLY game with a great engine that also plays well is BF3. Usually the better gameplay will be the one with the worse graphics though.
