Great thread; I thought about making one on this topic a couple of years ago. I'll just stick to the five I watch (Colbert, Fallon, Kimmel, Meyers and Conan).
Best Monologue: Tie: Colbert & Kimmel
I love Jimmy Kimmel's monologue as his delivery and attitude are great. His only weakness here is that he tends to interrupt his monologue with lame comedy bits interspersed throughout. Fallon's monologue is the worst as his delivery is not great, but it's not very long either.
Best Skits: Tie: Colbert & Conan
Everyone is a bit hit and miss here. Colbert has the "Big Furry Hat" and "Latenight Confessions". Kimmel is the worst as far as skits. I love "Mean Tweets" and when Yehya critiques movies and "Unnecessary Censorship" is ok, but Guillermo and Cousin Sal are boring. Seth has "Ya Burnt!" and a couple of other good ones but whenever his writers are featured they're horrible. Fallon's good ones are "Superlatives" and "Thank You Notes"; Conan has "Celebrity Surveys", "What Am I Watching", "Mascots who shouldn't Dunk", and of course, "Clueless Gamer".
Best Writers: Colbert
Brian Stack is funny as hell. He used to be with Conan (Wikibear!) but is now with Colbert and is featured regularly. The worst writers are Seth Meyers'; not that they don't probably write good jokes, but whenever they are featured in skits they are terrible and not funny at all.
Best Band: Colbert - Stay Human
Jon Batiste and his band are just awesome. Even heard them playing a Zelda tune once as they went to commercial.
Overall: Stephen Colbert
Colbert is my favorite (hilarious, smart and lovable) but I make it a point to watch all of them up to when their guests come out. The only exception is Fallon who I don't care if I miss. He tries to be too hip for his own good. Likeable guy, just not that funny or the best host in the world.
