However, especially when I was a undergraduate, I found it very helpful to look through at least one other book in addition to reading the required text (of course, this is also in addition to carefully re-reading notes taken during the lectures). The following is a list (in alphabetical order) of other complex analysis books which I have found useful. The comments are based on my own observations and opinions (i.e., feel free to disagree with me).

1.

This book is a mix of introductory and more advanced topics. Admittedly, I have not read very much of it, but, when confused on a particular topic, I often found it very useful to read the applicable discussion in this book, as an alternative approach.

2.

This is the book I learned complex analysis from as an undergraduate, and I highly recommend it as an additional reference for extra examples and exercises to practice solving. The main drawback of this book is that it does not discuss the more general case of some of the results, which are covered in the Marsden and Hoffman text.

3.

This is a more advanced text than the Marsden and Hoffman text. As stated in the title, the explanations are quite visual, and the approach is from a much more geometric point of view. I initially found this book's explanations rather difficult to understand until I had learned the corresponding material from a more "standard" point of view; then, the explanations were much clearer, and they helped me to solidify my understanding by approaching it from another perspective.

4.

Technically, this is also a more advanced text. It is generally used in the UCD graduate class on Complex Analysis (205A), but, in my opinion, the first five chapters are certainly accessible after (!) you read the applicable sections in the Marsden and Hoffman text. Then, it goes on to cover some interesting topics which are not covered in 185A, such as the gamma function and the zeta function (which appear frequently in some areas of research-level mathematics), and conformal mappings.
