In terms of value, here are our thoughts:

CHRIS: I have a rule that if two food items I’m deciding between are within $5 of each other, I’ll just buy the one I prefer. In this case, Burger King’s Whopper would be the slightly superior deal, but you have to pay for cheese so I’m docking a few fractions of a point. However, they’re a significantly better deal per-ounce, so for that, they outscore McDonald’s here.

KRISTA: I’m not going to lie, I don’t love the fact that Burger King makes you pay for cheese on a sandwich feels like it should already come with it for the full experience. That being said, yes you are getting a LITTLE more bang for your buck with the Whopper. The BK patty doesn’t even come close to adding up to the size of the two patties on the McDonald’s Big Mac. So, for those reasons, the Whopper wins on value.
