I think it's all business economics. The Sony channel extended and extended eliminations because they wanted the revenue from the ads so even Ritwik Dhanjani had to leave because he didn't foresee the extensions of five weeks. He already gave those dates to Star Plus.
As far as dance except Akash M who is still in baby stages everyone is the kind who if the choreographer delivers, they can win.
But Akash M adds huge draw because of his strangely mature way of talking. I don't know why he is getting lower votes. If channel wants to keep him on because he is entertaining.
