Bowley, Roger; Sanchez, Mariana's Introductory Statistical Mechanics 2nd (second) edition by Bowley, Roger; Sanchez, Mariana published by Oxford University Press, USA
I used this book for my undergraduate statistical mechanics class. Found it to be a bit too wordy and long-winded, and I also did not like the fact that important equations and concepts were not written in a way to stand out at all from the clutter. However, the text did include a lot of interesting discussion on the concepts and some good problems and solutions at the end of each chapter. Not sure how it compares to other statistical mechanics books, but compared to other similar texts I have used on mechanics and thermal physics I would say it is sub par
