Noida Extension 3BHK: Is the build quality a myth?

Noida Extension keeps coming up every time I shortlist something. I'm currently in a 2BHK in Indirapuram and thinking of upgrading to a 3BHK, maybe in Sector 150. Already have a home loan, so the EMI jump needs to be justified. Everyone glorifies builders like Godrej and ATS for their brand, but nobody talks about the actual construction quality post-possession. Okay, I'll say what no one says: are we just paying a premium for a brand name when the plaster cracks or seepage starts after a year? I hear mixed reviews even for Mahagun or Gaursons projects there. Is it worth paying ₹1.2 Cr for a 3BHK if the finishing is sub-par and maintenance charges are extortionate? Honestly, post-possession charges are a huge concern. Change my mind.
