in case you didn't notice, neither Wayne nor Jeezy are text heads.
being able to sit down and write a dope punchline does NOT make you good at hip-hop, lol... its an art homey... and soooo much deeper than that.
the logic you're using would make JR Writer or Gillie Da Kid both better emcee's than Tupac...
its an art, its more than "dope punchlines."
