The C&C courses near Scottsdale provide an interesting contrast of opinions.
In general, my favorite courses provide a sense of seclusion (I like when that occasional wayward drive won't cause personal or property damage!) and a feeling of an escape. I like to walk when I can and I really enjoy architecture that challenges and heightens the overall experience.
For me, all three courses provide a unique opportunity to walk, not something common in the desert. We-Ko-Pa and Talking Stick represent two very different pieces of land. I thought the playability and variety in the North Course at Talking Stick was fantastic. There's some incredible architecture to be found throughout the course. Honestly, the South Course was not to my tastes. Water in the desert has never felt right to me. We-Ko-Pa is so dramatic. The movement of the course over that property is exhilarating although in some spots exhausting. The architecture, challenge of the course, seclusion, vistas, all hit the mark for me. Whenever I get to Scottsdale, my first choice is We-Ko-Pa but my second choice is Talking Stick North. Any other accessible course in the area falls short.
As far as The Warren Course at Notre Dame goes, let me just say if that is what many believe to be one of C&C's lesser thought of courses, I hope my professional career be anywhere near that bad!
