Gerry Blair's book is a great read; local high school has recommended it to some of her kids that weren't interested in most other literature to get them interested in doing more reading. One of my favorite reads.
As far as the magazines go, my first thought when I read the post title was "20 round Pmag in FDE". Kidding aside, they all say a lot of the same things, just different ways with various amounts of advertising. I take FFG just cause of the diversity in it.
