Noida Extension: Which builder delivers on time?

Hey everyone, I'm looking to invest in Noida Extension. I'm mainly concerned about project delivery timelines. Has anyone here bought from Godrej Properties or ATS Infrastructure? Which one is generally better at delivering projects on time? I've heard mixed reviews. Kya aap logon ko pata hai about their track records specifically in Noida? Also, what's your experience with their customer service after possession? Which builder is more responsive when it comes to maintenance and resolving issues? I'm really confused. Mujhe advice chahiye! What do you think? Thanks!
