Noida: Which builder delivers projects on time?

Guys, I'm planning to invest in Noida. I'm confused between a few builders. Delivery timelines are super important for me. Has anyone experienced significant delays with a specific builder? Which one has a better track record for on-time delivery? Also, what about the quality of construction? Is it worth paying extra for better quality? Kya aap logon ko pata hai about the after-sales service of these builders? Which one is more responsive and helpful after possession? Mujhe advice chahiye regarding this. What do you think? Any suggestions would be helpful! I'm looking for genuine feedback. Thanks!
