Noida Extension: Which builder is more reliable?

I'm looking to invest in Noida Extension. I've heard mixed reviews about different builders. Specifically, what's everyone's experience with project delivery timelines? Which builder, according to you, delivers projects on time more consistently? Also, kya aap logon ko pata hai about the quality of construction of different builders? Which one uses better materials and has more durable construction? I'm confused between a few options. Mujhe advice chahiye regarding which builder offers better value for money in the long run. Any suggestions or personal experiences would be highly appreciated! What's your take? Has anyone here bought property recently?
