here's some deep thinking for you... anybody who says ANY rapper is the greatest of all time is overrating them.... who the fuck are any of us to say who's the greatest of all time at this point. as far as i'm concerned, a better rapper can come out in the future that's better than 2pac, biggie, rakim, etc... so when this rap shit is over (which we see no signs of), then we'll determine who the greatest is.
and yes, he is overrated because there are so many bullshit dickriders out there who treat him like he's god or something.
