Noida buyers, which builder's delivery is actually on time?

I'm confused about builders in Noida. Heard mixed reviews. Supertech ka toh naam hi kharab hai, right? But what about actual possession dates of ATS projects? Are they sticking to the timelines they promised? My parents keep saying check the builder's history properly. Honestly, not sure how to find out if they delay projects by years. Anyone faced major delays with a particular builder? Batao yaar, ab samajh nahi aa raha.
