I don't think you're making a fair comparison. Let me give you an example:
Who is funnier Ray Romano or George Carlin?
What TV show was funnier Everbody Loves Raymond or The George Carlin Show?
IMO ELR was boring and formulaic but, GCS was just plain unfunny. However, IMO George Carlin is 100 times funnier than Ray. I don't even think Ray is qualified to carry George's luggage, but Ray's show was funnier.
Is Carolla funnier than Stern? IMO yes, but Stern's show is funnier because of Artie, Fred and Robin.
But, this is all my opinion and I'm as full of s*** as everybody else.. so, who knows??
