The 8th edition of this Biology book is great. It has many pictures, diagrams, and charts that make the reading much easier. Also, it has end of section reviews that help to absorb the material.
If you are required to purchase the 9th edition- don't bother. When comparing this version to a classmate's, I noticed that the text and charts were essentially the exact same. The 9th edition has nearly the exact same content, except some diagrams may have different colors or be located on different places on the page. So, if you already have the 8th edition or can find it somewhere for a lower price than the 9th, there is no need for the 9th edition.
