First, the physical product was well-packaged and arrived without damage.
Second, it is a beautiful tome. My only quibble is that there was no hardcover option; this is merely a personal preference for hardcover vs. softcover.
Third, the content is exactly what it says on the tin. If ACKS is your bag, this is a must. While ACKS Core is eminently playable as-is, if you enjoyed the "rolling back of the covers" in the Player's Companion, this is your candy. Having all of Axioms 1-8 in a collected edition, with (I presume; I havent checked) the most recent errata and updates to same incorporated into the text is invaluable.
Finally, Autarch is a class act. If they publish it, give it a look. I have yet to be disappointed.
