What does WTO have that....

... these other books don't?

So the first poker books I read in order were:

Winning Low-Limit HE
SSHE
ITH
TOP

Then I bought Yao's book and for the life of me I didn't learn anything I hadn't already read in another book. Did I miss anything? Why is this book rated so highly?

I personally think the book is maybe 7/10. If you haven't read SSHE or ITH it could be considered good, but those books together pretty much cover everything you need for LHE until the middle limits+.

Can anybody tell me anything they learned that they couldn't get from the above books?
