Jeff,
They are confusingly similar. I've had both in hand and have spent endless hours trying to identify birds. The clues that have me leaning towards Cooper's are that the original poster thought it was a Peregrine; a big female Cooper's is about the same size. Then the fact this bird blasted through a screen window. I just don't see a sharp-shinned hawk doing that (though again, a big female...). But mainly, the head is just too big for a sharpie in my opinion and the tail looked rounded (this is hard to ascertain with a ruffled bird but a sharpie has a squared off tail).
Really, the only certainty is Accipiter species.
Paul
