biggie and nas are good but no one comes close to Em. no one had rhyme schemes as deep and only few can match him in storytelling. his flow was always great but just kept getting better over the years. imho he is the goat with no match.
discography wise he's not even top 30
yes his rapping is great but his music itself isn't enjoyable imo. biggie's flow is the best ever and it's not close
