Nas made better (studio album) music with God's Son compared to BP2. That was literally the last time he did that until what, 2012? SD came out a year after The Black Album and sounded terrible in comparison. I'm not even a fan of AG but it's objectively better than the Def Jam Nas albums from around that era (HHID, Untitled). By far.
This is literally the string of albums/time that separated them as artists in the minds of a lot of people. It's the period that popularized (not birthed) the talking points about beat selection. It caused an entire generation of kids to grow up thinking Jay was better, bigger, etc. I'm not saying I agree with that conclusion, I'm just saying it was a rough time to be a fan and Nas didn't truly get back to greatness until 2012.
I remember when What More Can I Say came out. Granted I wasn't in NY but that shyt was a massive "he's back" track to everyone I knew, rap forums, etc. Virtually every track we heard before the album dropped (except Change Clothes) was crazy. It was an undeniable classic record and that's when the pendulum swung. I vividly remember "wait until Nas responds to this shyt" sentiment because that's the timing I was on. And then we got Street's Disciple...
