I can agree with this. That said, I really don't think there is much of a difference between the crusts at different pizza places, even comparing mom and pop and chains. This is especially true when you get into the thinner, New York style pizzas because the crust is so thin you can barely taste it, anyway.
On the topic of crusts, I've never understood why stuffed crust isn't more common; it's incredibly easy to make and so, so delicious. When I was overseas I used to make homemade stuffed crust pizzas and it blew the minds of the foreigners who tried it.
