manhattan review practice tests

[ds01]

I realize there are numerous threads about GMAT practice tests concerning Kaplan, MGMAT, Princeton Review, Veritas, etc. I was curious if anybody had any data or anecdotal evidence about how the Man Rev practice tests compare to the real deal. My only issue is that the verbal seems to be significantly harder and up for interpretation than the practice questions I have been doing in the OG12 and OG2 Verbal/Math (and I'm thinking of complex idioms on fourth question of test, hard science based reading comps with 5 paragraphs for first four questions, etc.)

any help is appreciated.
