To bring more validity to my argument:
36 Chambers, Forever, and the W are about equal or close to Infamous, Hell on Earth and Murda Muzik
Now let's take a look at their albums after those initial three:
Wu - Iron Flag, and 8 Diagrams
Mobb - Infamy, Americaz Nightmare, Blood Money and the Infamous Mobb Deep
That's 2 albums from the Clan. One, I admit was totally lackluster (Iron Flag) but 8 Diagrams was a very underrated album that caught flack partly because of Rae and Ghosts sabotage job.
The Mobb had 4 albums after Murda Muzik and none reached the unbelievable quality of the first three official Mobb albums (I'm obviously excluding Juvenile Hell). A lot of throwaway tracks on all of them, including the one that dropped this year.
