Agadmator is a mediocre player (as in no titled) and his analysis are pretty simplistic but he has created a good community of kids around his channel and he is a nice fellow.
For actual analysis of quality you could check out the Chess24 channel where you have guys like Peter Svidler and other GMs analyzing games. The Spanish version is great too, you can find there all the top Spanish speaking players (Dominguez, Vallejo, Anton,Granda, etc)
Agadmator may be "mediocre" (aka still better at chess than anyone I've ever met in person) and his analysis simplistic, but that might actually help him on his mission. Which seems to be to make chess as consumable as a mainstream sport: nearly immediately following a game, he gives you the highlights - just enough so that the game has an exciting narrative, even if the analysis is not extensive.

I enjoy watching on my lunch breaks. Great breakdowns of games between top players past and present.
