AFfC is better the second time around. The first time, with all the new POV characters, is jarring. You don't know them and the characters you want to hear from aren't' present. It makes the book grind in the Iron Isles and Dorne for the most part. ADwD, at least, brings back a lot of the characters you want to read, even if they are not at their best. One of them isn't quite as frequent, but those chapters have terrific pay off in both books.
