So what exactly is different when buying Penrose X or Penrose? Is it strictly color scheme or is the dongle included different in some way? If I plan on getting both the PS5 and Xbox Series X, should I get one over the other?

I tried using the search function for looking in this thread but it keeps saying it found zero results so I'll ask here: If I plan on getting the PS5 and the Xbox Series X, does it matter if I purchase the Penrose or Penrose X? I read somewhere that the included dongle is different in each...
