Far as LT2, yeah it got a good number of good songs. But not many great ones, and ain't cohesive at all. Vernon Family is dope but it sound like something recorded around HHID era, you got other stuff that sound like it was recorded around 2015, Queens Wolf is a funny concept but needed another verse. It really feel like a collection of B-sides and throwaways recorded over 10 years.
Whereas LT1 was recorded 1998-2001 for the lost classic "real" I Am, and Stillmatic. So it sound focused and cohesive and it was Nas in his prime. They almost should have called it Death of Escobar like the title floating around in 2000 and thrown a few more of the unreleased tracks on like Rise and Fall and Amongst Kings on there. But it's near perfect as is.
Vernon Family IS from the Hip Hop Is Dead era. LT2 is a collection of songs from the Def Jam years (06-12) so its a longer period of time and more albums than the time between I am and Stillmatic.
