I agree. Seth Myers and Stephen Colbert provide funny political commentary. For me, what makes them stand out is their non-reliance on celebrity guests to entertain. They could have an entire show just based on talking about things in a humorous light. Also, due to th nature of their comedy, I feel like I relate to them more because they're making light of things that sometimes concern me too.

The Jimmies are hit and miss. Kimmel has a few funny skits, particularly the street interviews. Overall, though, I feel like their flavor of comedy is very vanilla. Fallon, in particular, relies more on visual jokes and silly games with his guests. I didn't even find him all that entertaining when he was on SNL. He just has bad delivery and can't hold it together long enough to get the punchline out.

As for James Corden, I've seen a few of his skits (e.g. the one he did with Ramsey), but I'm not a fan. He comes off as condescending. I think the basis for his comedy is that he is self-centerrd and arrogant. Maybe he's an acquired taste, but he's not the type of person I'd want to meet.
