PHX is a very good airport its just the right size, easy to navigate, and not long lines. My experience was good except for a rude Delta employee, and a rude TSA agent yelling at the Pre -Check passengers, myself included. The food options in terminal 3 were minimal just a Starbucks and a Wendy's. Taking a morning flight out of PHX is a big plus because the sunrise is amazing especially when taxing to the runway (great photo-op)!
