PHX is fine - lots of better airports, lots of worse airports. The decor is ugly and dated, and it's way too spread out (Terminal 4 ALONE itself is way to spread out, and that's just one terminal), but everything (including the bathrooms) are always clean. The new car center is beautiful, but SO FAR away even by shuttle. This is not an airport you can cut it close. Food is hit or miss - they've got a Oaxaca and a Paradise Cafe, though, so it could be a lot worse. They try hard to be the "friendliest airport" with lots of roaming friendly volunteers anxious to provide you help as well as free wi-fi (which is spotty and weak).
