Many people claim Jay Z won vs Nas. To those people I say.
And yeah dont allways agree with most things, but DX is on point about raising some discourse in Hiphop context. Somethings better to ask good questions then to try provide the answers.
And beef aint requirement at all, even if its sometimes apt way to test your skills vs another. For example 2pac beef with Bad boys for me as a serious listener was more embarrassing in MC level (fluffy puff piece songs) despite all the entertainment that came out of all that. Was dark angry period in his life, even if he pretty much clowned whole bad boys well and good. But its his passionate artistic fervour and album collection that sets him apart, not the beef superiority, despite how iconic the whole west and east coast thing became.
Andre 3000 has big backlog with his duo but as he has not released a single solo album (tho speaker box/love below is essentially half solo album) let alone solo song, so he pretty much kinda takes himself out of the equation (requires comparing head to head albums of each rapper in most cases) even his insane skill level is undoubted.
