Bill, I've printed a bit on Duratrans, which I believe is very close to Duraclear (I think one base is transparent, and one is translucent). And I've printed a LOT on Cibachrome/Ilfochrome. IMO there is NO comparison. Kodak does have a newer print material, KODAK PROFESSIONAL ENDURA Premier Metallic Paper, which sounds like it might have some of the old Ciba look, but this is only for digital output. Don't know anything about Fuji materials, I've moved on to gum bichromate for color printing.
HTH,
Denny
