I generally trust IGN, GameSpot, Edge, Game Informer, and 1UP.
ONM is ok, but I have to wonder with them being so closely affiliated with Nintendo if there isn't an agenda at play.
GameSpot's text reviews for NSMB, Nintendo Land, and Ninja Gaiden 3 are up apparently too, but with no number rankings. Seems like NSMB U and Nintendo Land reviewed quite well, while Ninja Gaiden 3 is an improvement from the PS3/360 versions but still flawed.
