I'd been somewhat concerned that this was going to be just a big punch 'em up. I was pleasantly surprised. The plotline is one of great important to X-Men comics, dealing with the return of Phoenix and what comes afterward, and it's dealt with quite well. At times there's a bit too much plot over characters, but in many of the issues characters still manage to shine through. (I think Bendis and Aaron do the best job at various points.) My only major problem with the core store that the way that five certain characters start to act dramatically out of character halfway through the comic. Yes, there are good reasons for it, but it feels very artificial and we don't really empathize with them afterward. Still, a great story with great repercussions [7/10]. 
 The additional books in this collection, the Infinite and the AvX issues, aren't actually that important. I think the storyline would be just as good without them, and I'm unlikely to reread them if I read the series again. Still, the AvX were generally enjoyable and I thought the last two issues were particularly good. [5+/10]. 
 I do have two complaints about the physical hardcover. First, the idiots at Marvel mar the art throughout by pasting stupid "ARs" on it, so that you can scan them with some artificial reality program (knocking yourself out of your reading experience while you do). NOT COOL, Marvel. Leave the art be. Second, it's glue bound which means it's hard to read stuff toward the margins, which is a struggle throughout the book. I don't know why they went cheap on the binding of this $75(!!) book when they could have given it the omnibus treatment. These two elements detract enough from the comic to bring my rating down. 
 (If I were just reading a TPB of Avengers vs. X-Men #0-12, without the stupid "ARs", my rating would probably be higher.)
