I would add Sebonack to the list.
We are talking "most architecturally interesting" and not "best" or "perfect"...simply the most interesting courses architecturally.
I think at Sebonack you get to see the mixing and melding of two distinctive styles. And you end up with the thrill of Nicklaus golf tee to green, the wonderful routing of Renaissance Golf Design, and the wonderful turf and views of Southampon, NY.
Furthermore, you get the undulating greens that Renaissance is famous for (and these just might be the greens that changed Nicklaus' green construction style) that are, at times, stimped too high. This adds interest in my mind as you get to see what people mean when they say too much contour and too much speed don't mix.
Also, you have a wonderful routing that is jarred a few times by out of place design items...like the pond on 8. Again, I think this adds interest architecturally as you can literally feel the flow of the routing and the course broken the instant you come around that corner on the 7/8 transition.
Adding it all up, I think you get a really good golf course that has a lot of interest and food for thought for the architecturally minded golfer.
