I actually find some 3b1b content really useful. When I was learning linear algebra his course provided a visual representation for the fundamental operations and properties, which helped solidify and consolidate the formal stuff. The LLM videos are great too (ref https://xkcd.com/1838/).
To be fair, I think visual representations are particularly useful for reasoning about vectors and transformations, and I think I retain less from the videos that focus more on a specific advanced problem rather than the fundamentals of a topic. Those videos feel a bit more clickbaity too.
