Their big beef is that Utah does not recognize the greatness of Booker. The Jazz fans on Reddit's biggest beef on Booker is that in every single Donovan Mitchell thread for his first two years in the league Phoenix fan would always break in and have to talk about how much better Booker was. It was tiring. As far I know, Jazz fans don't break into every Ja Morant or Luka thread demanding people praise Donovan Mitchell. Utah has its insecurities, but that was a whole new level.
The truth is that most Utah fans didn't care one way or another about Devin Booker, until Phoenix fan demanded that we pay homage. Screw them. And now that they added Chris Paul, screw them harder.
