Was PowerScore Bibles REALLLLY That Good?

<p>I took TestMasters for the LSAT and found it pretty decent. </p>

<p>I had taken philosophy classes in college before that had already introduced me to much of the core concepts of logic, so perhaps was already at an advantage, but nevertheless found TM pretty helpful. </p>

<p>I have friends that seem to swear by the PowerScore bibles ...particularly or Logic Games...and now I'm wondering if they're REALLLLY that much better than the other material out there (primarily vs. Testmasters)?</p>

<p>And, if so, what makes them so good?</p>
