I have repeatedly read that these two films are essentially the same material just aged differently. I would like to take the opportunity to say: these films have little in common apart from both being Kodak E6 films. The colors look distinctly different, with the Elite Chrome having a much more artificial and unnatural look. Whatever the difference may be, it's not from aging or storing, as I have mistreated E100VS badly but still got very similar looking results out of it (if this means I don't look carefully this should tell you how different the Elite Chrome looks if even I see huge differences).
