He's okay! He fills an important niche and has a lot of good info. The main caveat I'd want to encourage considering when watching his content is to just consider his perspective. He's a medical doctor first, and he's had whatever list of experiences he's had. He speaks with authority on many things and comes from a place of expertise, but even within those fields there will be disagreements. So I'd mainly watch out for his prescriptive judgments.

In particular, his stance on cannabis could use more nuance. He admittedly has never used it, so a lot of his concerns and hesitancy are based on whatever other data might inform his perspective. Cannabis research is severely lacking and there's a lot we don't know about it. Given his audience, he really does need to broadcast caution with it, as it is still a psychotropic drug and can still contribute to mental health issues in certain cases. And he goes pretty hard on that front, encouraging people to beware of the effects of it. It's just disappointing when his conclusion always seems to be abstinence.

He recently dropped a new video saying that "discipline is an emotion" which seems like a pretty dubious claim. I'd like to rewatch it to understand the science behind it better but it seemed like a sort of sensationalist claim that discussed the emotional experience of "resoluteness" and ways to cultivate that experience. It seems interesting and useful, but definitely something to take with a grain of salt, not as gospel!

TLDR: Good content creator, well-informed doctor, has his own biases and perspectives, learn & listen but question before following. I recommend him to other clinicians whenever they're struggling with a young male client.
