Godrej delivery promises often miss.

Spent the whole Sunday checking out options in Sector 150 and Noida Extension. Honestly, Godrej ke projects ka delivery track record thoda shaky lagta hai from what I've seen, especially around the Yamuna Expressway belt. But unka build quality kaafi consistent hai, no doubt. ATS ka on-time delivery better hai, but sometimes finishing mein chhoti problems suni hain. Gaursons ka toh mixed bag hai, my friend faced delays in their previous project but construction was decent. What's the real scene with hidden charges for these builders? Matlab, possession ke time pe suddenly PLC ya maintenance deposit ka shock lagta hai? My budget is around ₹1.5Cr for a 3BHK. Any firsthand experiences with these specific builders in Greater Noida?
