The Norris who beat Leonard vs the Benitez who beat Duran. Personally, I think El Radar would have outclassed Terry and stopped him late.
Benítez shows him what real talent is. Terry's fast hands could land a few nice shots, but he doesn't have the tools and intangibles of a Hearns or a Leonard, which is what you needed to beat Benítez below 160.
I have to go with Wilfred El Radar Benitez, over Terry Norris. Bemitez did get stronger at 154 lbs, he still retained his speed in his title winning knockout of Maurice Hope in 1981. Norris had good hand speed and could hit, but Wilfred would be hard to hit in this one, Benitez by unanimous decision.
LOL! In all seriousness, I thought only punchers tend to trouble Norris, but I forgot that Benitez did have occasional pop at 154. And a peak Benitez would be hard for Norris to hit consistently, too.
