Pretty good!
I had also bought his original SSFIV (pre-AE) guide in the past, and one thing I wish this AE one had that other included was a list of anti-airs for each character! Also, it seems to be missing Ibukis new 10th target combo (cr.HK -> cr.HK), which got added for AE.
Other than those minor details, it seems to be just as good as the old one and more!
