Depends on the type of crust.
If it's stuffed crust than it's the best part of the pizza. If it's just thick crust than it's an enjoyable bread stick.
If it's thin crust it depends on how cooked it is. If it's burnt you might as well be eating a stick of burnt cardboard.
I never really understood eating the crust first and working your way down, because the crust is meant to double as a clean handle you can grab while eating the rest of the pizza, but each to their own.
If you bite a pizza from the side first instead of top or bottom, I don't know what's wrong with you.
