Saguaro is pretty good. It feels geared to match play, in my opinion, given how many half-par holes there are and some weird tongues and wings in the greens. Talking Stick may be a better use of its property, but Saguaro is a better golf course.
Desert Forest is very good, if a bit hard. I prefer it to Estancia, although that is a fine Fazio effort. I have not seen Scottsdale National's Other course, but I want to.
If it's me, I might go to Saguaro or Desert Forest.
