I don't know anything about the Russel book, but I recommend the two book by the Szamatulskis without hesitation.
I've actually only brewed a few recipes verbatim from them,. but they're an excellent source for getting a basic idea how a number of classic styles are brewed, how, say, Guiness differs from Murphy's, and so on.
Anyone who has the brewing bug will get a lot of enjoyment from those books, even if you don't brew a bunch of the recipes.
