I've read various William Gibson books and generally enjoyed them, but I find his dense writing style exhausting sometimes. I think a comic written by him could work pretty well.
J. G. Ballard comes close; The Atrocity Exhibition is very Gibsonesque in places, though with a much bleaker sense of alienation than anything Gibson wrote. Cormac McCarthy is also great, though not like Gibson at all.
People seem to like Neal Stephenson's early work (Snow Crash in particular), but I was always put off by his apparent plagiarizing of Gibson's style.
Edit: Also James Ellroy.
