How sure are you about this? We switched over to XMF a while ago (over PRINERGY due to costs). We do a LOT of business with Fuji (~$30,000 a month), so I doubt they would price gouge but I can't help but wonder if we've paid a premium price for nothing.
After having seen them running in parallel on 3 different computer one near each other, I can assure that it's the same piece of software with same features but only different color in the interface mask.
Check and compare them on these youtube videos
