Depends on the person. For me, they are people who I respect and trust to provide unbiased reviews/releases. ACG (Karak), Civvie11, GmanLives, MaximilianDood, PeanutButterGamer, AntDude, SomeCallMeJohnny, HappyConsoleGamer, etc. Streamers, Youtubers, they tend to be far more honest about the games versus most of the "mainstream" gaming "journalists".
IGN, Polygon, Kotaku, PCGamer, RockPaperShotgun, etc - all have proven time and again that they do not care about games, gamers, or quality. They will shit out whatever they want with a disregard for any basic journalistic integrity or quality control.
Though there are definitely some you want to be weary of. Folks like James Corden, GameXPlain and the like - blatant console warriors/platform shills who have as little integrity as the aforementioned shitstains above.
