After years in real estate, buying my own 3BHK

My lease ends in 3 months, finally buying a 3BHK in Sector 150, around ₹1.5 Cr. I know the marketing spiel, but what's the real ground reality for Godrej Nest vs ATS Pious Hideways on on-time delivery and construction quality? Any hidden issues post-possession? Also considering Gaursons; what's the community's honest take on their projects?
