I like this youtuber pretty lefty from this and other videos I've seen. Also I've found the info in the builds useful when playing dnd.
Better to check out the video then me trying to describe how much I like him.

Tulok's video style basically requires this, because otherwise he'd just be giving the exact same advice over and over again, but his builds are always pretty terrible. Going straight Swashbuckler Rogue and taking feats like Martial Adept (instead of the painfully weak Athlete) would be much more effective than this multiclass monstrosity, but luckily 5e is pretty forgiving of people making suboptimal choices.
In one of his builds for tmnt he more or less mentions that had he gone full monk it would be too out there for what the the turtles can do so more flavor instead of powerful.
