Best AP US History prep book for the 2015 test?

What is the best prep book for the 2015 test? I know that AMSCO is very good, but does anyone else have anything to say about the new editions of companies like Barron’s, PR, 5 steps to a 5, etc.</p>

Also, is there not a 2015 ediiton of the Crash Course (PEA) book available yet?</p>

<p>Crash Course is not released annually. If you need a content, and not study book, try AMSCO or Essential Content.</p>

What I’m hearing is, Essential Questions is a bit outdated now, though it was amazing in 2012.
AMSCO is what I’ve heard everyone say, but it should also be mentioned that it’s over 700 pages, even though it covers everything on the AP test.
Adam Norris’s videos are apparently really great.
And Crash Course for APUSH is amazing to brush up on key things right before the test.

Wow, I’m a year off. Ha ha, sorry.
