Although I do like dungeness crab, it doesn't have nearly the flavor of a good blue crab. And I'm not talking blue crab from Florida or somewhere in Asia. I'll take Chesapeake (or even better, Choptank River) blue over any other food any day. But again, you gotta go to the right place......or do it yourself.
Oh I have had Chesapeake blue fresh from the water.... and I have had dungeness fresh from the water (and that is the key to both of them).
Dungeness has plenty of flavor but one must eat it in the proper manner which is to say a bath in the pot of water and then to the plate. Blue crab is better in a crab cake of some such mixture ( to my taste). I will take a pan seared soft shell over just she crab any day of the week
