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)
