WHAT WORKS: The sheer amount of detail on the mindset and process of the Mastermind (especially) and the Grifter is very helpful. The "Dozen Grifters" and "Dozen Masterminds" is also useful for giving some ideas on how to make characters of those roles who aren't just Sophie or Nate renamed. The alternate settings sections was also fun, and basically any ideas on how to NOT just be playing the Leverage crew renamed is always welcome.
WHAT DOESN'T WORK: A lot of the GM advice is nothing special that you haven't seen before. I'm also not quite convinced that the Masterminding the Rules section successfully provides that mechanical bridge for Masterminds that some folks feel was missing compared to Hackers, Hitters, Grifters and Thieves.
CONCLUSION: An unessential but incredibly useful book for Leverage. It doesn't dramatically change anything from the core rules, but it does provide some very useful tidbits on Grifters and Masterminds, both as PCs and NPCs. Basically, if you really like the Leverage game and either want some more options or are struggling with the Roles at all, it's well worth it. And don't complain about the extra books: There was a time when each role (including Fixer) would have been padded out into its own book.
