Oh and also Tyrannicon for his "TJ Lazer" Space Scumbag Mass Effect 3 LP where he dubbed over Shepard for the whole game:

Don't let the name put you off. It's a gaming channel dedicated mostly to console games, both old and new, as well as the occasional PC title. Very knowledgable, great information on collecting as well as homebrews for systems like the Atari 2600.
You kidding? Metal Jesus Rocks is an awesome name. Now I get a picture of Jesus rocking it out.
How the last supper really went down:

What is a gaming channel?
Reviewers like AJ and Total Biscuit are enough for me.
I rarely watch short playthrough videos when I'm stuck in a place/mission in a game.
I only watch short playthrough videos if I don't have the game and want to see how it's played. In the case of FrankieonPCin1080p though, he makes his videos actually entertaining with his edits and since it's only the AMRA2/3 and DayZ videos I watch of his, they are videos to be watched since everyone's experiences in those games are different.
And yeah, the reviewers you mentioned are the only reviewers I watch too on their reviews on games. I haven't found any others who don't bore me when reviewing a game and they are quite honest and address the details I always want to know, especially Angry Joe. So many reviews babble on with exaggerations, Angry Joe gets to the points especially when it comes down to an RPG.
