Nas
Nas could do crossover club records. Despite what anyone says You Owe Me @ Oochie Wally were hits that ting off to this day.
Jay could NEVER do Rewind, Second Childhood, or One Mic. He’s got nothing of that creative caliber in his discography.
I'm sure if you polled just regular hip hop fans on social media it'd probably be Nas (I notice this all the time on most hip hop posts and shh!t on IG, the love Nas gets compared to Jigga)...if you ask celebrities it's probably gonna be Jay-z. Kinda similar to Kendrick vs. Drake.
They live in a alternate universe
