Okay I understand your point on that.
I think my unpopular but I guess strangely also unpopular opinion is that in both those specific cases those pairings were so perfect that no OTHER rapper has been able to consistently sound as good on those 2 super producers beats. No one finds a pocket crafts a hook flows on Preemo / Pete beats like CL & Guru....
And another unpopular opinion i think both those mcs kinda sorts resented the fact that they become permanently attached to one single god level producer like and never really able to venture on their own
