The pitch "textbooks suck" seems so disrespectful and tasteless, it literally makes me avoid that book. Most of my uni textbooks did not suck at all.
If I needed to fill a gap in my knowledge or learn a new subject I would never resort to a textbook until I had exhausted every other available option.
Helena Curtis wrote a wonderful college level intro textbook as of 1980 when I last used it, but the publisher (Worth) let it die after she retired (which also pretty much killed them as I recall).
