If I can help I'd say, figure out who represented their area best and from those pick your favorite, instead of just picking what looks good. Maybe that helps maybe it doesn't.
I suspect SF's was a great clone from the comments in the thread, but I've never had that sandwich before - looked great ...
Having said that, Scovie's Skyline-like entry was killer, so killer - in fact - that it reminded me of the best clone job I've ever seen ... Scuba Steve's White Castles from our slider TD!!!
I am on the fence but was able to quickly narrow it down to two. Scovie did nail the Cincy mole chile and that carries high marks in my book. But then there's Grant's perfectly-cooked, juicy slab o' beef that was thinly sliced like sandwich meat should be. I guess I'll be Twispertated until I actually vote.
