Since the two were across the parking lot from each other near where we stayed in PHX over the weekend, I got both to enjoy together.

Can't agree with you on the overrated thing. I'm not a snobby socal in-crowdie, and I think in-n-out is the best fast food burger I've had anywhere. We were there for 5 days and I had a single patty cheeseburger(In lieu of a double double, to minimize the impact on waist and arteries) 3 of those days.. and 1 of the days they were closed(thanksgiving). In-n-out is a must anytime we are near one.
