Tim Minchin is pretty entertaining

It's a toss-up between Prophet of Zod, Seth Andrews, and Cosmic Skeptic.

Seth Andrews and Thank God I'm an Atheist.

George Carlin

Seth Andrew, The Thinking Atheist podcast.

Unfortunately neither of my favorites are very active anymore but they both have catalogs of previous work that are great. Non Stamp Collector created atheist animations and Edward Current did religious satire skits. Both guys are terrific.

Aronra for me. It’s fun to watch him bash religion because he’s good at it. What I really enjoy a lot more though are his vids on evolution. Especially his classification of life series. When I wanna feel amazed and confused as hell without being high, I watch him talk about paleontology.

There used to be this French kid dressed up like a monk making absurd creationist arguments. Same angle that darkmatter and mr deity take. It’s gone now but he had this awesome chart about how all the slowest animals were found in the deepest rock layers and all the cheetahs were near the top because of how long they could outrun Noah’s flood. He was so dead pan serious about it that ya had to laugh watching him. I’m sad he took em down.

I do not follow much A/Ag content these days.
I do watch Paulogia fairly often though.

Here are two more I would add to the list: Darkmatter2525 and Valerie Tarico.

These days I'm really into Paulogia. I also relate pretty well to Genetically Modified Skeptic. In fact, I'm friends with Drew McCoy on my alternate FB account. Of course, I love me some Aron Ra (even though he can be a bit of an asshole lol).

Cosmic skeptic is heady but great, holy koolaid is pretty legit, dark matter 2525

Aron-Ra

I like bionicdance. Check her out at youtube.

One I don't see here is Christina Rad. I don't think she's still active, but I could watch her forever.

Don’t really watch any, but I’ve caught a few debates and like the reasoned responses of Stephen Fry best. Richard Dawkins seems too much like an evangelist for atheism for my liking. The late Christopher Hitchens was a brilliant polemicist and his erudition was just no match for anyone on the religious side of any debate.

Oh yeah, and they're not exactly a seriously intellectual channel, but Hugo and Jake are really awesome too. Really fun guys, if you're into cringe humor. Lol. But at least they disclaim it by reassuring people that they really do have decent morals, and sometimes a joke is a joke.

I do not follow or watch any. I am much more focused on history and classic literature.

Matt Dillahunty, Jimmy Snow, Amin Navabi, TellTale,

I loved the original Mr Deity stuff by Brian Keith Dalton - a great comic take on how silly religion is with his wife as Lucy aka Lucifer and another guy as Jesse aka Jesus.

Brian now does the more serious "Way of the Mister".

Atheism Is Unstoppable --

Aron Ra, Hitchens - even though his material is old now, Cosmic Skeptic.
