My recollection of a study bu US archivists is that if you need a slide that with the greatest life when projected, Ektachrome is best. If you want a slide with the greatest un-projected life, then it's Kodachrome. To put it another way, Ektachrome last longer than Kodachrome when used in a back-projection display panel, but Kodachrome lasts longer than Ektachrome when stored in a cool dark dry place. In my own experience with 50 year old slides of various types (both the above, Agfachrom, Gevacolor, Anscochrome, Ferrania, Perutz etc), Kodachrome is the *only* one worth considering.
