Bear can do no wrong in my mind and this was definitely the best Wild West steampunk I've ever read. Also, this book gets the award for the best use of a sewing machine in combat.

Unfortunately, I'm kinda not a fan of steampunk (or fantasy) set anywhere west of New York and I'm even a bit picky about the east coast as well. Actually, the last book I really enjoyed that was urban fantasy and set in the US was ALSO by Elizabeth Bear.
I enjoyed this one as well; Bear is just one of those writers for me. Not sure whether it's a 3 or 4 star book, but it seems unfair to dock points for writing in a genre I don't like.
