Amrapali or Supertech: kisko avoid karna chahiye?

Currently in a 2BHK in Sector 75, thinking of upgrading to a villa. Already have a home loan, so EMI isn't a big issue, but I'm hearing mixed reviews about Amrapali and Supertech. Kya kisi ko pata hai about their on-time delivery track record in Noida? I've heard horror stories about possession delays. Is it worth the risk, or should I stick to something safer? Also, construction quality wise, who's better? Heard there are issues with seepage and plaster cracks after a few years. Honestly not sure which builder to trust. Any advice from people who've bought from them? Is the price jump worth it for their projects?
