Against vastly inferior comp
That's like holding up the "superiority" of the dominance of a division 2 athlete over the high level competitiveness of a d1 athlete.
Beyond stupid argument
Absolutely.
Only Geto Boys have an argument of being greater than the 6 due to their pioneer status, longetivity and about equal level of influence.
None have a better and deeper discog than 3-6.
Yet Lord Infamous is every bit as elite, if not a better MC than the top rapper in every group you named.
Better producers, better rappers, better discog, better group.
