Is ATS's delivery track record reliable?

Sector 150 projects, especially ATS ke. I'm upgrading from my 2BHK in Sector 78, looking for a 3BHK. ATS ka delivery track record kitna reliable hai? Brochure timelines dikhate hain, but actual delays kitne hote hain, yaar? Mera already home loan chal raha, delay se EMI ka burden badhta hai. Kitna trust karein inpe?
