I don't know about that. The Contract With God Trilogy, City People Notebook, Last Day In Vietnam are by far some of the greates works of sequential art ever made. The Spirit will always be my favorite "superhero". Eisner, along with Jerry Iger, also started Kane, Kirby, and Lou Fine on their careers. Sandman may be my all time favorite graphic novel, but Eisner was, in my opinion, the authority on the medium. Since he died only recently, and since he worked right up to his death, I think it would be fair to consider him a part of the modern US comics creators. Combined with Speigelman and McCloud (Boston baby!!!) I'd say that puts the US at the same level as the UK, if not above it.
