This is a real tough call for me. IMO the Morales/Barrera/Pacquio/Marquez rivalry matches the fab 4 for competitiveness and then some. All great fighters. Morales seems to get the short end of the stick, but he was awesome in the first PAC fight. I imagine he was for the first MAB fight too. Did all those wars wear Morales down for the rematches? They all had tons of experience. Who's better? I can't say.
