I've loved Letterman since the beginning..... When he's funny he beats them all.
I think anyway.
I never got over how Leno had to be so damn "aw shucks" in his Tonight Show guise since he landed that gig. I did see the show once live last year and he was cooler during the pre-show warmup.
Conan gets on my nerves no end. So smarmy and obvious.
