First of all, most of these channels aren’t even specifically focused on Physics so i’m not sure this is the right platform to ask this question. That said, i can still help with the personal experience i’ve had with some of them. Pbs Spacetime is probably the best specialized channel on Physics. The content is accurate because of the fact that they don’t dumb it down to the point that it loses meaning like other channels and matt (the show’s host) is himself an Astrophysicist and an accomplished one.

Kurzgesagt is somewhat accurate but still kind of shady. I’ve often noted that they’re a little too optimistic when it comes to some of the science, to the point that its not objective anymore. I’m a fan of optimism but i keep all this stuff outside the lab. They’ve often taken up material from questionable studies or research papers and have presented it as actual science and they’ve been rightly called out on it as well. Other than that, i do often get the feeling that they don’t know what they’re talking about in rare but real instances.

Ted is just a joke, to me at-least. I don’t know about the other channels on the list.
