I rarely disagree with them, and if they bash a them, they actually back up their views unlike one website who whines about the game throughout the entire review. For Edge, they are the only ones I can trust for PS3 games. They are extremely unbiased when it comes to PS3 games.
Worst: IGN. They overrate a lot of PS3 games, and they bash games without backing up their claims or providing good reasons.
