Well, Henry Armstrong trounced the ATG Barney Ross for the WW title and then beat the #1 WW contender all while weighing within the 135-pound limit himself. That's about as big an achievement as any lightweight had while still actually a lightweight.
Having said that, I usually rate Leonard and Armstrong #1 and 2 at the weight respectively. I rate them both over Duran at that weight (both in achievement and H2H) as I don't believe Duran beat competition on par with their's at 135, and besides which I don't think Duran really reached his peak until moving up to 147.
