I think Letterman is much funnier than Conan. Conan does a bunch of goofy skits that are entertaining sometimes, but most of the time they just annoy me. Letterman is much wittier and off the cuff funny, so I prefer his show.

I always find myself watching Conan until I see Letterman is on.

For some reason David Letterman just always has something different on and Conan can be a bit monotanous at times. So all in all I watch Conan O'Brien but I prefer Letterman most definately.

Letterman is absolutely hysterical, and I love the history behind this guy. I've been watching his show for years, and only got into Conan last year. I love Letterman, and will always remain true to him!

Letterman is a combination of comedy styles...old and new. I think that's why he's made it this many years. I remember him in stand up and he was hilarious then. When Jay Leno took over the Tonight Show, I was heartbroken but Jay did well these 17 years as the head of the most watched TV Late Night show and he always mixed it up well. O'Brien is a bit too quirky for my taste but he was in line for the gig and he's got it now. I wish him luck but I think he wasn't groomed for a show like this. We'll see and in the meanwhile, I wish him luck.
