This, so much this. And these have been the two main publishers I've had to deal with. And all the course content is structured around their organizational modality because the professors just dump their slide decks in lecture, except naturally much of the nuance is lost so, necessarily, one must have the book. However, I won't pay for it because I'm not going to support rent seeking that is totally degenerate, but I do get it free. And even overlooking the dreadful formatting, the writing is often bad. This was especially true if the mathematics textbooks I've had to deal with.
