Classic Game Room. Very entertaining reviews(so entertaining I actually watch reviews of wires, bottle openers, etc.), a lot of the time gives good information.
For information on games that youtube channel doesn't have, I might sometimes check IGN for a quick rating. I don't care for the number scoring system for games, but if it gets a 1, I might want to be cautious.
