I thought the latest edition of Beckman >> Blueprints. Blueprints stopped trying a while ago, it's way too sparse on detail and there's no logic to how they present anything. Beckman is the official ACOG book, and you can tell they at least make an attempt to be a complete resource. Case Files and Pretest were also good. I ended up with the high score on the mini-board in my group, so it worked for me.
In any case, you certainly don't need Beckman AND Blueprints, just pick one.
