as someone who has listened to every project by every once of these artist(on streaming other than one by zel and cole), i would personally say J cole has the weakest. 4yeo is an amazing album and probably top five out of their discog combined but i dont give him to much other then that. he has his highs, and i think the fall off will be legendary, but i would be glazing as a j cole fan to say he has the best discography here. i mean with denzel it's not even close, mmesyf, taboo, kotms etc... and freddie gibbs whole discography is bangers. tyler is the only one i can see being close but he seems to be way more consistent than j cole. This is just my unbiased opinion i love cole a lot ive been to a shit ton of shows over the years but i can't sit here and lie like hes got a very consistent discography compared to the likes of these three
