I watched many of the games of this series live via this channel, and it was great how the commentator had his own board to demonstrate the next few moves and explain the players' thinking. It was really interesting and relaxing.
I've watched most of his videos on his YouTube channel. He's not the most experienced player but his style of communication is very accessible, even to casual chess players. I'd especially check out his videos on Leela Chess Zero and Google Alpha Zero; they are a blast!
I also loved elements of the chess.com stream, especially when guys like Levon Aronian and Hikaru Nakamura come on, but there's something to be said for just a very high quality stream with somebody who both knows what he's talking about and is super humble and interesting.
