Cel shading can look good but Champions Online's take on it looks awful. With City of Heroes there is some disparity between the content, but the game is 7 years old so that's to be expected. The most recent additions look tons better than what Champions Online (e.g. the revamped Atlas Park, the Steampunk, Barbarian, Circle of Thorns, IDF, Alpha costume sets, the Time Manipulation, Kinetic Melee, Demon Summoning powers).
