I think it's an outrage that Psmith isn't universally recognized as the best Wodehouse character. Psmith's in his own category at the top. Then there's the second tier which includes Bertie, Jeeves, Ukridge, and Uncle Fred (hope I'm not leaving anyone out). Third tier is Gally, Emsworth and one off characters like Piccadilly Jim. The Mulliner stories are some of the best, but you can't say the Mulliner character himself much qualifies.
