So, to me, Duran's 'No mas' was significant more for the perception and popularity of the two fighters at the time, rather than that Duran was a super threat to SRL's dominance of his own weight class at the time.
That win against SRL really cemented Duran's greatness in stone. SRL fought the wrong fight. That is one of the main reasons why Duran is Top 10, higher than SRL - but this doesn't have much bearing on SRL's greatness at the weight, especially considering he went to avenge his loss and also beat other ATG's.
It's not accurate to say he 'jumped' two weight classes. He fought at 140lbs a handful of times before his last fight at lightweight, and had 8 fights leading to the SRL fight, with 1 being a great win against a Hall of Famer (Carlos Palomino).
I do believe Duran was better at lightweight though, and eventually weight issues and ring age got to Duran.
