ATS Destinaire vs Jaypee Kasa Isles: Which is better?

I'm confused between ATS Destinaire and Jaypee Kasa Isles in Noida. ATS is under construction, but Jaypee is ready to move. Carpet area wise, which one is better? My wife wants good amenities for kids. Has anyone experienced possession delays with ATS? Kya rates sahi hain? Mujhe advice chahiye, yaar!
