Game Chasers don't know shit about games except how much they cost. When they asked Jay and the other panelists what game was the most precious to them in their entire collection during a Q and A at Magfest, everyone else answered almost immediately. He faltered and then asked "You mean which one is worth the most money?"
I think that sums it up pretty well.
I don't see the appeal of the Happy Console Gamer! He's knowledgeable and he has a nice pile of games but he just, like, talks? I'm not his friend. I don't really care to see that. Plus his shelves are REALLY ugly. Don't buy a game for a week or two and invest into that.
Turbo Views is great because the Turbo is so neglected in the retro scene and Chris Bucci is an awesome dude who you can tell has a real love for the games.
My picks would be:
Game Sack
http://www.youtube.com/channel/UCT6LaAC9VckZYJUzutUW3PQJoe brings amazing production values to the show, and both dudes are knowledgeable and care about the games. I can do without the fanboy personas but I get the feeling they're a bit exaggerated to give the show some flavor. I don't always agree with what they say but they know what they're talking about and they play f*cking EVERYTHING. If you do a show on the X68000 you are legit as f*ck, sorry.
Splash Wave
http://www.youtube.com/channel/UCtt_NEKZ4MoH4O7BT3SbXTAAwesome looking euro-centric retrospectives by Strafefox. Just watch a couple. It's criminal he gets so few views and lazy garbage like Game Grumps or PewDiePie are incredibly famous.
The Happy Video Game Nerd
http://www.youtube.com/channel/UC5Xeb9-FhZXgvw340n7PsCQI don't like his stupid face and I don't like his stupid wine, but I can't argue that he has done some great reviews for some great games over the years.
Honorable mention goes to Roo from 16-bit Gems. I just love that guy.
