Electrostatic vs. Boxed vs. Ribbon?

I have audition Martin Logans, which have a nice dark background with superb clean and pinpoint imaging. B&W Nautilus and Revel Ultimas which are really dynamic, but not as clear and precise in imaging. And also the Carver ribbon speakers which are closer to the box speaker than the Electrostatics. Can anyone help me emphasize on the pros and cons of each of these 3 speaker designs?
