They both did their things...they did them. You love Nas for painting pictures with words and just saying shyt that sounds dope...you got that. You love Jay-Z for his wordplay and entendres and his prestige/coolness on the mic, you got that. Idk why yall have to make it a competition...but I will partake, lol. l think it's a preference thing, off the first few listens I prefer Jay-Z's verse only because I am a wordplay, double/triple meaning type of fan at this point in my hip hop fandom...and even beyond that he was saying some hard shyt. But even saying that its madd close, it's a 51% to 49% thing, Nas was dope on here...I could probably end up liking his verse more than Jay-z's the more I listen.
The video itself is kind of ass tho, madd underwhelming and boring, it actually makes the song feel more blah than it is.
