Finally upgrading – Antriksh Grand View or Anchal?

I'm currently in a 2BHK in Sector 75, thinking of upgrading. Antriksh India Grand View looks good, but it's almost double the price of Anchal Silver Oak Tower! Is the price jump worth it? Carpet area mein kitna difference hoga? Already have a home loan, so EMI is a big factor. Anyone has experience with Antriksh specifically? Heard mixed reviews about builder trust. Is it too risky to consider Anchal, since it's under construction?
