Under-construction properties in Delhi are a bad investment gamble.

Did a site visit to Sun Freedom Floors 2 and Ashoka Enclave last Saturday. Honestly, under-construction projects like Sun Freedom Floors 2 (which is like 30-50L) are a big gamble. Everyone glorifies the "new amenities" but nobody talks about the hidden risks of delays and builder track records. Ashoka Enclave, though older, feels more solid, ready to move, no RERA headaches, no waiting for possession. My current 2BHK in South Delhi is fine, but I'm thinking of upgrading to a 3BHK. Is the price jump for something like Sun Freedom Floors 2 really worth the stress? Builder ka track record bhi dekhna padta hai. I'm worried about rental potential too for under-construction ones; kaun wait karega? Ready property ka rental yield pakka hota hai. Plus, hidden costs like PLC add up. Disagree? Tell me why.
