No - at least, not to me.
TR = fiction, with plots about random stuff that he uses to launch into long, deep philosophical rants/lectures about different topics. (I am not really a fan)
CK = non-fiction, writes essays - basically each book is a collection of essays written for newspapers and magazines - where he takes a cultural phenomenon like John Cusack, heavy metal, Saturday Morning cartoons, etc. - and describes why that phenomenon seems to matter to a large swath of the public (including himself) and what that affection tells us about ourselves. Not particularly deep, but insightful and funny. Observational.
