I've had Ray's Hellburger, and it's definitely in my top 10, but you have to realize, my favorite is Fuddrucker's, so take that into consideration when dismissing considering my opinion.
I do like In-n-Out and Five Guys, too, but...they're still fast-food to me, these ^^ are restaurant burgers, and I sort of use different scales for them, I don't know why (I mean, they're still burgers, right?).
