The Scott robertson book goes very in depth about drawing using perspective and cross sections. It is entirely focused on that, with design and rendering reserved for future books.
Sketching the Basics has not nearly the same amount of information about perspective drawing, but it does have a lot of other stuff about color and how to present designs. I think its more advanced in general. I would go with How to draw because the video content is great and the fact that it really is more about drawing rather than how to be a designer.
