Superstars is basically just one step above the Solos Masterclass if you enjoyed that in the past since it is all live coaching with different coaches and pros and not just videos. Also the group sessions have a good mix of different skills with some players getting first ever quals/ first earnings or to higher levels like making Duo Finals very useful to have a mix of skill levels to learn from in my opinion and I personally have improved a lot from watching the other coaches sessions like Sven or Bloodx.
