Biggie by far. Pac was kind of a terrible rapper - always helf-yelling and shit. His influence has a lot to answer for.
And I'm not mad @ Biggie's output - quality control is important, but Pac and (mainly) Suge didn't give a shit.
just milk the weird cult of personality surronding Pac for all it's worth.
I do appreciate that Pac was more real, more three-dimensional with his personality than most rappers.
Most dudes come off terribly when they rap about anything but money, coke, or how nice they are,
but Pac seemed like an actual human being. Too bad he couldn't rap.
When it comes down to it, Ghostface is the only rapper I've heard who can be "emotional" yet is still undeniably dope.
