neither--they are both fattening and a disgrace to our society--
over 60% of americans are obese because of these two fast food chains...
besides, meals at both of those places are at least $5-$6 now, why not just save your money and go to a nicer place w/ better quality food, for example olive garden has all you can eat breadsticks, salad & soup for only $5.99...
I think this would be a much better choice
