I respect PAC and his legend, have all (if not most) of his released stuff but I rarely set out to listen to him specifically. But like most mcs (not crazy about the term, rapper - an old school thing) I enjoy him in a hip hop mix. And, no I don’t regard him as the best mc ever to have spit. Don’t see the point in crowning anyone. Hip Hop is far too varied to narrow an appreciation down to a few gifted individuals who might have been influential but still part of the whole wide fabric of the genre.
