I've always preferred Vol 1. The beats on The Prophecy are better than anything on Vol 2 IMO, they sound a little crackly and low-key, but that's half the appeal.
I'm not too big on Immortal Technique, his creativity and use of language is often stunning, but he just comes across as arrogant and more than a little boastful most of the time. There's only so much brag rap I can take, regardless of how well it's written.
