Bundini is spot on!
However, here's my take per division:
Heavyweight: Ali-Frazier 1 and 3
Light Heavyweight: Sugar Ray Robinson-Joey Maxim. Robinson was winning on all fronts but he lost due to heat exhaustion. Since they were fighting under the same sweltering condition, props have to be given to Maxim.
Middleweight: For ebbs and flows, nothing beats the final fight between Tony Zale and Rocky Graziano. Watch it on you tube. Hagler-Hearns pales in comparison.
Welterweights: Sugar Ray Leonard-Thomas Hearns 1
Jr. Welterweight: Aaron Pryor-Alexis Arguello 1
Lightweight: Beau Jack- Ike Williams--it's war!
Jr. Lightweight: Bobby Chacon-Rafael Limon final fight
Featherweight: Marco Barrera-Erik Morales, it was civil war
Jr. featherweight: Wilfredo Gomez-Lupe Pintor
Bantamweight: Carlos Zarate-Alfonso Zamora, battle of the KO kings
Flyweight: Humberto Gonzales- Michael Carbajal---the first and only million dollar fight at flyweight.
I'm going to have to make my list from fights I actually saw.
Heavyweight- Lyle vs Foreman
Light Heavy- Franklin vs Lopez
Middleweright- Hagler vs Hearns
Welterweight- Leanard vs Hearns I
Lightweight- Corrales vs Castillo I

Floyd Mayweather vs. Pacman or Tyson vs. Mayweather
