depends.
i prefer a good or great hamburger over a good or great brat.
i prefer an average or below-average brat over an average or below-average hamburger.
it's far easier to mess up a burger than it is to mess up a brat. i can be pleased with a burned brat. overcook the hamburger, however, and not even the condiments will save it. on the other hand, i think a standard brat with onions and mustard has a capped potential. the possible gap between solid and exceptional is not sizable. but a standard hamburger with onions, pickles, ketchup, and mustard still has the potential to make one's knees weak. moreover, the possible gap between solid and exceptional for a burger is virtually limitless.
because of these variables, i could not submit a vote. sorry.
