People are really divided on which course they like better since the two, North and South, are so different. Both are very good tests. Personally I like the South course, where the PGA held its Match Play until it moved over to the Ritz. Wide fairways with lots of contour so flat lies are somewhat harder to find; huge greens that belie how difficult it can be to 2-putt. The North course has more elevation changes and doesn't fit my eye as well, but is still fun to play.
The biggest problem is that the members decided to make it more exclusive and have drastically restricted outside play, so it's nearly impossible now to get a tee time unless you know a member. Too bad.
