Conan is the only guy that brings out fresh, new jokes.
Pretty much he's the only one that makes me laugh.
I want to cry when I watch Leno, I don't understand how people can laugh while watching it...
Letterman.. lost his edge I suppose, he's getting old, I never really watched him earlier so I wouldn't know.
Jon Stewart makes me laugh sometimes.

The rest are horrible. Carson Daly? Pffffffffffffff. It always seems to be on because it's right after conan and I end up laughing at how pathetic a host he is, and the fact that his guests don't even like him, they're just there for the publicity.

Jimmy Kimmel is an asshole, so no, I don't like him.

Others I haven't seen, probably not worth watching anyways.

Conan is the only one who makes me laugh.

Sometimes I watch Leno because there's nothing else in the time slot, but his monologues are usually dead silent until they flash the "applause" sign and his bits are just plain boring. It amazes me that Leno has any show whatsoever.

Conan by far. Letterman used to be that good.

Letterman is only funny in a bitter old man sort of way. Which makes me wonder why I don’t visit old folk homes more often. Oh yah cuz they are BOOORING.

O'Brien is the man.

I voted Conan. I want my kids to go to Harvard so they can be smart and funny like him.

That was a joke.
