Kansas City Gates sauce on the rear chop, Stubbs Mop pre grill and a coat of Stubbs Sweet Heat. Both got a dusting of rub and the chop without mop got a little oil.
Visually they look the same. The Gates Sauce has a nice spice to it, but the more I use the Stubbs mop the more I like it. Then the sweat heat comes in nicely.
Close call, but I'm giving it to Stubbs.
