The Best Schiele of all?

So, which painting is the best of all? Is it his self-portraits of anguished disfigurement? Is it his bleak landscapes with arthritic branches? Or is it the tortured and faceless female nude that haunts those solitary paintings? Post your suggestions, please! My own favourite: it won't surprise you to hear that it is not the Sunflowers recently sold at Christies but rather the brittle love of Friendship above.
