imho its Hearns because he faced REAL opposition...and although he didnt come out on top all the time...he never ducked an opponent and always fought with serious heart and fierce power...he was a beast in the ring and goes down as one of the greatest WW/JMW of all time... RJJ will go down in history for being the guy in over a century to go from MW to HW champ across the board and his showboating was something spectacular...that will add some sparkle to the whole career... but his opposition was a bit questionable...a bit... but he was still an amazing boxer and legend...
