See our review of the second edition.

The most significant change made for the third edition is a reorganization of the material on unique factorization in domains, “reflecting that for many teaching a first course this topic is optional.” That required also reorganizing the material on ideals.

I am a fan of the rings-first approach to algebra, agreeing with the authors that students’ familiarity with the integers and with polynomials renders rings more intuitive and accessible than groups. But this book has many other virtues besides presenting the material in this order. For example, each section is preceded and followed by short sections that try to put the material into a broader context. As the authors say, students first learning algebra tend to get lost in the details, so this attempt to make them notice the landscape rather than just focusing on the stones in their shoes is to be welcomed.

This is definitely a book worth considering for textbook adoption.
