Best Rounds between two great fighters?

Hagler-Leonard round 9 never gets mentioned but was pretty thrilling.

 

Barrera-Morales I round 5

 

Benn v Barkley round 1

 

Round 4 Holyfield v Foreman

 

They called it the ''Double H Battle Royale,'' between Hopkins and Hakkar. Marvin Hagler was quoted as saying "I came up rough in my generation but I never saw anything quite this rough." I would see all the rounds for that.

 

Hopkins-Trinidad round 10
Holyfield-Foreman round 7

 

What about round 7?

 

Great round but dunno if you would call them great fighters

 

Maybe that’s the round I was thinking of but I believe round 4 was when Holyfield got hurt and you thought big George had a chance

 

Bowe V Holyfield - round 10.

 

I consider Ken Norton to be a near-great, but that 15th round vs Larry Holmes was for the ages.

Shout out to @quintonjacksonfan for mentioning Pryor-Arguello I first round — saw the thread title and figured Hagler-Hearns round one would be Exhibit A, but came to post Aaron vs Alexis opening stanza.

 

Round 14 of the Thrilla in Manila.

 

Moore / Durelle I - Round 1

Moore's resilience and instincts are palpable.

 

Oscar vs Ike round 12
Marquez vs pac
Oscar vs Shane had many great rounds
Ettiene vs cley-bay
