In their primes, who would win between Roberto Duran vs Julio Cesar Chavez?

At lightweight Duran was pound for pound one of the greatest of all time. He would win. He was the total package you name it. Offense, Defense , Killer Instinct and Power. He would decision Chavez and outpoint him easily over 15 rounds. Chavez was great. He did not do one thing great but he did everything well making him a complete fighter as well. Now at the higher weights jr. welterweight and welterweight i would go with Chavez via a decision. This is a great match up.
