Tupac's verses were often way too long. Just listen to California Love and I Ain't Mad At Cha, each of them are 5-6 min long.

That's not to say Pac wasn't talented. I just think Biggie's style was better. Pac was all about the hood, Biggie was more about bitches and hoes. But I would give the edge to Biggie. I mean Biggie had Puffy and Pac had Dre, and both of them went on to lead successful careers.

But listen to Hypnotize...that song is so damn catchy.
