I think TDS Colbert is actually legit TDS, as in, he's actually insane. Kimmel is a sleaseball two-faced backstabber who hurts his own crew for signalling purposes (such as the firing of a 20-year-vet for a petty vindictive reason).

I think I find active malicious agents more unlikeable than the raving lunatic on the street corner screaming that a lawfully elected president will kill us all unless we all surrender all rights and freedoms to large private multinational corporations like Pfizer as soon as possible.

Neither are good to have, but good ol' fashioned crazy is more... pathetic and sad than unlikeable.
