With Azzarello, for me at least, I wouldn't rank him as the worst because I at least really liked her for the most part. The same can't be said for how Finch, Robinson or Wilson wrote her.
Where he falls short is the changes to her origins and the Amazons.
He basically wrote an awesome Image comic about a Wonder Woman expy dealing with Greek gods in the modern age, it just happened to be published as actual Wonder Woman where a lot of the ideas don't quite work.
