>both use stage names that are a pun on their actual initials ("MM" and "IW")
>both used to be a transgressive, edgy shock jock persona that was really an ironic satire of our fucked-up society
>both had an edgy alterego (Em was Ken Kaniff, Ian was the Content Cop)
>both are currently right now a champion of black lives and trans rights... without ever selling out
>Both had high profile feuds with other artists and spit fire diss tracks back in their faces yo. Em beefed with ICP and Triumph the insult dog and won. Edups beefed with Leafy, ricegum, and Sam Hyde and won every time
>both were major influences on younger rappers. (Ian was and continues to be a major inspiration to Joji)
The only difference I can think of is that Ian has a happy and healthy marriage, unlike Em and Kim
