Both in my top 3 of all time. Nas 1, jay 2.
Both have dropped multiple classics.
Nas
Illmatic
IWW
Stillmatic
Jay
Reasonable doubt (always been a classic to me, but make no mistake, this album came and went as far as NYC perception was on who is on top of the game during that time, don’t forget the source only gave it 4 mics during a time when the source was hiphops bible).
Blueprint
But both have dropped average to weak projects
Nas
Nastradamus
Streets disciple
Hip hop is dead
Nasir
Jay
Blueprint 2
Blueprint 3
Magna carter
Kingdom come
Vol 3
Nas will always be the GOAT in my opinion, IWW is not better than RD or Bluepront. but he has a better discography and less throwaways than Jay.
