Its an unfair comparison tbh
Not just cause its big shoes to fill but Michael and Nas are at different parts of their career when they linked up with Quincy/Hit
And honestly other than Dr Dre I dont know if any producer can be a Quincy to any rapper, theres just a lot going on with that direct of a comparison to just be a producer its to develop the artist.
I think an accurate comparison for Nas and Hit Boy are when an older legendary Rock muscian goes on a run great critcally acclaimed albums and its usually helmed by some younger A&R/Producer. Like whoever did Springsteen's albums the past 20 years that have gotten acclaim and grammys or like when Rick Ruben starts working wth legends. He actually did Johnny Cash last album before he died and many considered it his best work and it was in 2002. It was also part of a series like Kings Disease, called American (Released a series of them 1-4 before he died and then another 2 in the series after he died)
Actually now that I looked it up, the closest comparison to Nas and Hit is Johnny Cash and Rick Ruben releasing their volume of albums in the 90s and 2000s is a good one, cause they were all critically acclaimed to and respected by the purists.
