I think Katt Williams is hilarious when he is on and he isn't going through too much sh!t. His mind is clear and I think that dude is genuinely side splitting funny although controversial. Kevin Hart aint really that funny and is just the next n!gga in line. He is the anointed one. Ced, Steve, Bernie, all those guys have pretty much matured and Chapelle is god knows where, and Kevin Hart in my view is just the next dude, regardless of how funny he is. Dude is borderline slap stick. No one ever quotes Kevin Hart jokes. At least no one that I hear talk about him. All I ever hear is "Alright alright alriiiiight" in a half retarded voice. That sh!t got old after a few days.
Louie isn't side splittingly funny but he is almost Seinfeldian. He has really good observations about things that are beyond mundane and makes that sh!t really funny and relatable. He is the best in the business at it at the moment. He is what other comedians who have been doing a while but haven't made it, strive to be.
Just my 2 cents.
