I agree...two totally different types of films, reversal and negative. Reversal, of course, has no printing stage to introduce variables (although my point about bad processing is still relevant).
Also Kodachrome had a unique dye set, which was (at least in its last years) not shared by any other film, not even Kodak's own E6 family of films.
