rap is an element of hip hop..

break, rap, DJ, graf

it's like a chant.

but i agree that biggie and pac were over rated.. don't get me wrong, both MC's were good in their own way,

Pac could tell a story
Biggie could flip a line in so many ways

Pac could convey emotion amazingly
Biggie could hit you with a decent punchline here and there

but there will never be a G.O.A.T, and it's only 14 year old white groupies with afro wigs who think that there is one.
