I've already read and reviewed ABFE in general on the hardcover edition, but this was my first time listening to the audiobook. I think it was excellent, and love all the small things they did to make it a great performance. They were never distracting, and only added to the story. 

My full review is copied below in case anyone wants it:

I am reeling from this book. It's wild and big and weird and fascinating and I'm probably going to think about it for a long long time. It's somehow both very different from the first book, and also about the same core issues--just like, more fleshed out. What you get when you take those thoughts further. I will never not be in awe of Hank and these books.

Edit: After I wrote this review, I talked about the book with a friend and realized I had some problems with its resolution. So for the last two years I've been very sure that while I liked this book and series a lot, I liked the first book better. But I just finished my first reread of the book, and have some thoughts. I think it's just that there's one specific thing I find dissatisfying about the resolution, and aside from that I think this book is amazing. ABFE has a lot of things I find really useful and interesting, and I'm glad I reread it so I could appreciate it more. I like that these concepts are more fleshed out in this book than in the first one, and I think Hank really got where he was trying to go.
