Try the Living Greyhawk Gazetter. I'm a Verbobonc fan, I can't get enough of Elemental Evil.
Oooooooooo, Silverymoon area is very nice. But Generally I think you are right, the topography is either too heterogeneous, or uninteresting.
Uuuuuuuuum, I didn't like Western Shores, at all. I think Hero Games does Champions well, and creates quality genre monsters and villians for other genres, but the settings just leave me cold so far.
