Sohna 3BHK search: My take on builder transparency

Budget finalised, loan pre-approved – now stuck on builder choice for Sohna. I'm looking at 3BHKs around ₹2 Cr on Golf Course Extension Road. Considering Godrej, M3M, and DLF projects. From my experience, construction quality and hidden charges like PLC/EDC can inflate costs significantly. How are these builders performing on actual carpet area versus advertised super area in Sohna? Also, is their post-booking customer support reliable? Any insights on RERA compliance and surprises at possession for their projects? Transparency is key for me. Your opinions would be helpful.
