EDGE isn't biased against Sony and I don't think they're directly biased toward Nintendo.
However, they do seem to score certain genres and aesthetics higher while being more critical of others. Much the way Jim Sterling's reviews are more about "The Opinions of Jim Sterling" than they are about the actual games, EDGE reviews are mostly about their own pretensions.
I put Sterling and EDGE in the exact same category. Though they present themselves differently, the end result is the same. Both of them are useless unless your tastes align perfectly with their own--and mine certainly do not.
