Of course this is only my opinion, but I like this way to dive deeper in the heart of the subject, namely resist Voldemort. Certainly, there is less of magic, but the psychology of each character is reviewed in greater detail, which I appreciate particularly. The author's writing style seems to have matured, and I find that every moment of the book, although sometimes long, is not heavy. Clearly, this is the longest book, but it's the one I read faster. A true literary masterpiece.
