in terms of natural talent and athletic ability I say they're even, but Leonard has the better resume and not just on paper

he went 36 (25 KOs) with only 3 losses 2 coming at the end of his career, with wins over the likes of Benitez, Duran, Hearns, and Hagler, that alone is better than anyone that Jones beat, and Jones didn't just beat up on bums, both guys are great in their own right but IMO Leonard takes the cake
