I have been a long time subscriber of Kingscrusher.I dunno I just liked his energy.Also there 's Chessnetwork.I really liked Chessexplained's repertoire video series.And anyone there know someone who produces great endgame material in youtube?
The Backyard Professer, maybe??
in terms of annotating charisma or playing strength? but anyway-
Matojelic posts one or two videos covering a single master game almost every single day, he's one of my favourites.
Better KC than Mato, but this is my opinion. OnlineChessLessons isn't bad too...
Chess Network ala Jerry.
