Honestly, both are
In 2018 both of these brothers still put out albums that generated common interest in the both of them
Both are still equally relevant cause both's new input of music are still equally talked about today
Jay dropped the new album with Beyonce and got people talking and it was right after Nas dropped his joint produced by Kanye
Nas got people talking cause he dropped an album produced by Kanye who's been the talk of the town since his whole TMZ c00n moment.
So yeah, both are equally relevant to this generation I think
But what do I know, I'm an "old head".
