I found this book much more insightful than I expected and I know it added to my understanding of anarchism and how to more effectively make a case for it.

The two downsides I can think of are: much of it is repetitive, but that's the be expected given it's a compilation; and, Chomsky's Eurocentric view of anarchism. For him, anarchism is a European, Age of Reason, classical liberalism doctrine and nothing else. I disagree and think it's unproductive to define anarchism so narrowly.
