Noida under-construction projects — too risky or worth the savings?

Fed up of renting, landlord raised rent again! I'm looking at Noida. Dridha Homes is tempting with its price (₹30-45L), but it's under construction. Shubhkamna Apartments is ready, but carpet area seems less. Is the risk of delay in Dridha worth the lower price? What's the real story on possession timelines, guys?
