Best boxing lesson of this generation, PBF over Chico or JC over Lacy?

[SweetPea]

Can you narrow down what you mean 'Of this generation' a little more for me so I can narrow it down...

Thanks.

Let's say of the last 15 years

If it's last 15 years, then it's either Mayweather-Corrales or Whitaker-Chavez.
