I've not used chessable yet, but one of my favorite youtubers, John Bartholomew, is behind it and I'd recommend his videos wholeheartedly.

He did a series of videos that is particularly worth checking out called "Climbing the Ratings Ladder" where he plays opponents at different rating tiers and analyzes their mistakes[1].
