The two on the right have no redeeming qualities. Colbert was funny during the Bush years on the Daily Show. Oliver, despite his chronic liberalism, occasionally has some great segments highlighting injustices in society that are overlooked. And I have no opinion on the guy to his right because I've never watched his show. Of course, Conan shits on them all but he is thankfully absent here.
Pretty much the same reasoning for me. I've never watched Seth's show either, but I liked him on SNL and have been finding him funny on the Lonely Island podcast recently
I think I’d switch the Jimmys. Fallon sucks but has done some interview segments that are worth watching just because the guests are good at what they do. I hate Kimmel with a passion and even his interviews it feels like he’s actively getting in the way of it being entertaining.
