I just read an archived topic on this had had to put in my two cents. Boss, no question. People mentioned that boss would be more cunning and johnny has the edge in brute force, but I would go as far and say (even though I known Im going to be hated for this but...... boss> Maero> Johnny. Maero has been my favorite villin in the series. And if the boss can take him out...... sorry Johnny fanboys.
