Haven't used the Epson material, but do use LexJet backlight material. Seems about as durable as paper prints. Looks best on low illumination light boxes; if it's too bright, the blacks wash out.
I recently bought a HP z3100 and wanted to print onto backlit film for lightboxes. I talked to a few people who said that the Kodak stuff was actually the best. I bought sample rolls of both Kodak Universal Backlit 8m and Kodak Reversal Backlit. Both worked well but look contrasty and grainy, especially when compared to the Duratrans. Honestly, it's fairly good (about 80% of the quality of Duratrans) but no replacement for the real thing.
