What impresses the most is the quality of the projects and the clear and consistent layout, making the presentation of details that much stronger. Many other detail-oriented books presenting projects side by side tend to have drawings that vary in quality and content, making some projects more helpful to the reader than others, or just more interesting to look at.
The extra effort required to create consistent drawings pays off in the form of having a solid reference, rather than just a hurried and inexpensive collection of what's cool now.
