I don't think even Ahem Vin or Arpit have gained some huge benefits, they might have done leads but most of these shows didn't last long.
SRJ had been playing supporting roles since long, he was Vishnu in Devon k Dev Mahadev, funny thing is that Anshoor Kaur was a child artist in that show and played Ashok Sundari's childhood role.
SRJ was her Mamashri in DKDM and is now paired opposite to her in Patiala Babes.
Anyhow SRJ graduated from supporting roles to maib leads, Shaheer got the best of the shows and projects
So for me it's only KrishnaArjun who are the winners
