Louie is cool, but his comedy is too depressing and demonic. Cant fukk with him though. I know cac love that man to death though.
Katt Williams is funny as fukk. Granted he has fallen off seriously over the last few years, in his heyday (early 2000's) the dude was extremely funny. I remember laughing so hard at a show of his that i nearly passed out. But the bouncer let me meet him backstage cause he saw me laughing so damn hard.
Kevin Hart is also a funny mother fukker. Granted his comedy applies more to families and people with kids, especially black folk. That say it with ya chest line was perhaps one of the funniest parts of his act back in the day. But granted it sounds better live. I actually remember seeing Kevin back in 2005 in Detroit. The dude was funny has hell and there were like only 50 people in the damn room intended for 500. Dude has always been funny, but his comedy is more conversational.
Louie CK is funny, but he touched on alot of introspective and insightful type comedy. Its cool, but a different flavour from Kevin or Katt Williams.
