Fiorella's Jack Stack has the best beans ever, good sauce. Gates has the best actual smoked meat, the sauce is awful, Arthur Bryant's is greasy, but good. KC Masterpiece has really good sauce, but The Wabash sauce in Excelsior Springs, Missouri is the best in my book.
Have to disagree with you there. Jack Stack is a good restaurant. If you don't like tangy/spicy or thin sauces, then you won't like Gates.
