Which Noida builder offers better value for money?

I'm looking to invest in Noida property. What do you think about ATS vs Godrej? Which one offers better value for money considering price per sqft and amenities? Has anyone experienced significant delays with either builder? Also, what about post-possession maintenance? Which one is more responsive and provides better customer service after you've moved in? Mujhe advice chahiye, which one would you recommend for long-term investment?
