Which builder offers better value in Noida?

I'm looking to invest in Noida. Which builder offers better value for money, considering location and amenities? Has anyone experienced significant delays with a particular builder? Which one is known for on-time delivery? I'm also curious about the quality of construction. Is there a noticeable difference in materials used? What about customer service and after-sales support? Which builder is more responsive to complaints? Also, what's your take on resale value? Which builder's projects appreciate faster? I'm open to suggestions and personal experiences. Mujhe advice chahiye! Which would you recommend for a good ROI?
