The main benefit of dye-sub printers is that it puts a finishing layer between the color and "you". This helps the final prints resist fingerprint smudges and water spots. The ability to resist fading is inherent to the ink & paper, something that both technologies are (possibly) susceptible. If all other factors are equal, the dye-sub will give you more durable results. However, all other factors are never equal. The simple fact is that Epson has perfected the process of matching ink, inkjet, and paper to produce an awesome result. If you are willing to protect the print from fingerprints and moisture, the Epson inkjets are the way to go.
