Greater Noida builder quality claims are overhyped

Is ATS or Godrej construction quality in Greater Noida truly superior? We're upgrading to a 3BHK around Sector 150; our kids' school admission is crucial. My wife's priority is no post-possession issues like seepage. Gaursons' amenities look great, but I'm unsure about their long-term build quality. Any real experiences, especially from end-users?
