Out of the books listed, I've only read one, CISSP Study Guide, Second Edition, 2012, Eric Conrad. I am almost done reading the new CISSP Official Study Guide, 7th Edition - Sybex, which has become overly wordy for my taste. For people who need a book that starts from the beginning, this would be a good choice, but after reading Eric Conrad's book and having some experience it has become a second reference for me. Assuming you'll read at least one book and purchase some test questions, my pick would be the Eric Conrad Study Guide.
