Greater Noida builders: Delivery delays and quality issues?

Visited a couple of projects in Noida Extension last week. Honestly, I'm thinking of upgrading from my 2BHK in Sector 78 to a 3BHK or villa, but yeh builders ka track record dekh ke darr lag raha hai. Gaursons ka ek project dekha, but unka delivery kaafi late chal raha hai sunne mein aaya hai. Mera ek friend ATS ke project mein hai, usne bataya ki finishing mein kaafi issues hain, plaster cracks, seepage wagera. Itni high prices charge karte hain, especially for sectors near Yamuna Expressway, but quality control pe dhyan nahi hai kya? Is the price jump really worth it if this is the reality? Yaar, log itna EMI bharte hain, aur end mein yeh sab milta hai? Should I even consider these premium projects? Anyone else faced similar issues with these builders? What did you do?
