I do not believe there is a difference between Superflex and Five-Star. Back in 2013, Tom at PlayingCardsandMore (site CdnBeerLover references) helped me out by ordering full-bleed standard index setups that were not offered on his site (or anywhere for that matter) directly from Gemaco. I was thrilled, though the downside was I had to commit to a quantity of six setups, which I did, but I was able to get three setups Red/Blue and three setups Green/Brown. Once they arrived, the Red/Blue setups had the Superflex "S" logo on the back and the Green/Brown setups had the five-star logo on the back, but both the Red/Blue and Green/Brown setups contained the sames Jokers...emblazoned with "Superflex" artwork on the front side of the card. Also I think just by playing with them both it's clear they're the same card.
