I have played pretty much every Dye Course of consequence; a couple of early designs escaped my attention (people talk fondly about Radrick Farms in Michigan, which I missed) but I have visited/played all the "name" Dye Designs.
I think WS is absolutely great, as is the River Course at Kohler. I don't feel qualified to say that it's "better", "worse," "more derivative," than the Ocean Course, Harbour Town, PD GC, etc. I just think that it's a thrill to play, and I feel fortunate that I have played it 3 times to date. (Including most recently with occasional DG participant and long-bomber Shane Wright)
Personally speaking, my favorite Dye designs are The Honors, The Golf Club and PD GC, but some of that assessment has to do with the club ambience as well as the actual golf courses. WS to me is great though, on par with his other big-time resort courses.
