People eat crayfish lots of places. You aren't special. I used to catch them when I was a kid. And they taste like mud next to a lobster.
Personally I think dungeness crab is top of the pile, followed closely by king crab, then Atlantic lobster.
Nothing wrong with a crayfish. I enjoy them as much as anyone else with a seafood addiction. But they aren't comparable to lobster in the same way a catfish isn't comparable to a halibut.
