The theorems are more rigorous, requiring linear algebra, and I appreciated that.
The explanations are thorough and three times longer with diagrams that are much more illustrative. To other students in my class this book would likely be intimidating to them at my level but I found it much better allowing me to properly challenge myself and prepare myself for what my instructor would throw at me I used this book as a supplement for the vector calculus textbook (Hughes Hallett) used at my school.
