There's nothing overly remarkable about the Phoenix Sky Harbor airport at all, they simply get the job done.
Unlike SFO, they don't have many fancy dining options or nifty things to look at, they're just there to serve a singular purpose: to get you to your destination in a timely fashion. Can't hate on an institution that brushes off bells and whistles for a cut straight to the chase... so in the immortal words of Yelp's corresponding quip to a glorious three-star review, Sky Harbor, you're A-OK!
