-Conan is my favorite just for Late Night alone. I grew up on absurdist comedy though, I was watching The Kids in the Hall when I was still in elementary school.
-Space Ghost next up, for many of the same reasons, the same with The Eric Andre show, but I enjoy Conan and Space Ghost more.
-Letterman's stuff from the 80's to mid 90's was great, that show was the grandfather of absurdist comedy in a talk show format. Once they started culling bits like the Rupert Gee on the street segments and did less real sketches the show lost a lot of its' flavor, then Dave got bitter for a while before coming back at the end of his run.
-Ferguson was a grade A interviewer, never really cared about the monologue or sketches,always watched for the interviews.
-Johnny's show from what I remember and of course clips over the years that I've seen was always a laid back experience, especially in the mid 60's to 70's, I really like that aspect. I can't really comment on Allen or Parr.
-Dick Cavett and Tom Snyder were a different type of talk show, it'd be like saying Jerry Springer or Geraldo were talk shows (though they were something completely different themselves).
-Arsenio was cool for a while, he had interviews with Jason Voorhees and The Macho Man for God's sake! His comeback only hurt his legacy. He was fun to catch every so often when I was a kid.
-Kilborn, I always liked his Daily Show the best and his talk show was fun as well, though not as fun as his Daily Show run.
-I never really watched Later, so I cannot comment on it. I remember there was another one that came on late night on Fridays on NBC hosted by the wife of some studio exec that had a lot of bad sketches.
-Carson Daily, he seemed to care more about putting on bands than actually hosting a talk show, I think that's what his show turned into in a forum for putting on bands. I have not seen anything from the Youtube girl that took over for him.
- Never caught many of the short lived shows like Chevy Chase's, I did watch some of Dennis Miller's show and it was fine, but his HBO show was where he truly shined.
-Stewart wasn't a talk show host, he was a comedic news anchor who did one brief interview a show.
-Colbert on the Colbert Show was the same as Stewart on The Daily Show; as a Letterman replacement he stinks, the man used to be funny too which is all the sadder. I don't watch the show, can only go by the clips I've seen.
-Kimmel was fine before, the last 5 or so he's not even a shadow of his former self. I haven't watched in years, can only go by the clips I've seen.
-Fallon is just not my thing. Good energy, but comes across too fake.
-Leno I never really cared for when he was on aside from his man on the street bits, but seeing what we have now, his show is actually a bit nostalgic, not really political, classier and family friendly; I mean I still wouldn't watch it, I'd just feel better knowing it was on.
-Seth Meyers, just not my thing, seems better than Colbert and Fallon, but that's about it. I don't watch the show, can only go by the clips I've seen.
-Cordon, seems aimed more towards women aged 18-36 than anything else, not my thing. I don't watch the show, can only go by the clips I've seen.
