Artin is a top notch mathematician and this is very apparent from this book. The book treats the basics of abstract algebra in a really nice way. Furthermore, there are some nice additions such as symmetry of plane figures. If you want to start studying abstract algebra and you're looking for a nice first book, then this is the ideal book for you. Don't expect the book to be easy though. A course on proofs and logic seems necessary before doing this book.

to set the expectations and level, this was the sophomore level book at MIT. Those of us who would not even get into MIT thus may expect it to be hard. But it will repay our efforts. I have also taught from it at UGA. Mike's proofs are really clear, no hand waving and no cribbing from other books. he explains everything as he sees it himself, trying to make it come alive for the reader. he always sticks to the same level of exposition too, for (smart hard working) beginners.

This is where I first learned algebra. It is an excellent book, written in an "organic" style reminiscent of Arnold, Atiyah, Poincare, Riemann, etc.--the theory is always well-motivated, and abstraction for abstraction's sake is kept at bay. There are important topics not covered in Artin (dual spaces and multilinear algebra, for example), so you will need to go beyond Artin at some point. But for its intended purpose, an introduction to algebra, I can think of no better choice.
