I have both. The Swiss Army Original is has better contrast in daylight but barely glows at night. The Luminox glows brightly but not as bright as, say a Seiko, just after it has been exposed to the sun. Also, The original Seal watch larger and has a timing bezel. Of the two the Swiss Army tends to go better with a blazer and tie as well as sports clothes. Overall, though I think that I like the Luminox better, I guess just because it's cool. I don't have any experience with the customer service with either brand so I'll have to leave those comments to others.
