Ready to move is always better, fight me!

I'm looking at Lotus Greens Isle and Buildcon Maghad Mansion. Honestly, I'm leaning towards ready-to-move. My parents keep saying under-construction mein risk hai. Maghad Mansion is still showing as 'null', matlab abhi ban raha hai? I don't want to wait years! Plus, Isle has amenities you can actually use now. Is it worth paying extra for that peace of mind? Maybe I'm missing something? Anyone else feel this way? What's your take on possession risk, guys? Also, what's the carpet area situation? Ab samajh nahi aa raha.
