While I have not seen either of those books before, I have another book by the author of the first one, Stephen Blundell. It's Quantum Field Theory for the Gifted Amateur, and I think you might like it. Not as a standalone quantum book, but perhaps as a supplement to a more "serious" treatment.
Beyond that the usual suspects are good enough for me, I just don't like L&L. I'm probably forgetting something.
It's not exactly statmech but I really like McComb's introductory renormalization methods book.
