I broke this down once:
Illmatic >> Reasonable Doubt
IWW > IML, Part 1
I Am < IML, Part 2 (Hard Knock Life)
Nastradamus (TRASH) << IML, Part 3 (S. Carter)
QB Finest = Roc La Familia
Stillmatic = Blueprint
God's Son > BP2 (too much filler)
Street's Disciple < Black Album
Hip-Hop Is Dead >>> Kingdom Come (That album was TRASH)
Untitled < American Gangster
Life Is Good >>> Magma Carta
Distant Relatives > Any of those joint albums, but we'll just say Watch the Throne
Nasir < 4:44
Lost Tapes>>>>>>>>>>>>Best of Both Worlds, Pt. 1 > The Firm >>>>>>>>>>> BOBW, Part 2
That makes the score (not counting the last section of Lost Tapes/BOBWs):
Nas - 6, Jay - 5, with two albums being equal
