Amrapali or Supertech... who to trust in Noida?

Since January I've been trying to finalise a 2BHK in Noida. Honestly, I'm so confused after seeing so many projects. My parents keep saying 'dekho builder ka track record'. But ab samajh nahi aa raha. Has anyone had good or bad experiences with Amrapali or Supertech? I've heard stories about possession delays. Kya kisi ko pata hai ki actual construction quality kaisi hai after moving in? I mean, plaster cracks and all that. Also, hidden charges kitne lagte hain at the time of possession? PLC aur EDC ka kya scene hai? My budget is tight, so I can't afford any surprises. Any advice would be helpful!
