Unitech Exquisite is OC, but Purvanchal Silver Estate looks tempting.

Finally fed up of renting, so I'm looking at Noida. Unitech Exquisite is ready to move, right? But wo toh bahut costly hai. Purvanchal Silver Estate mein EMI kam lag rahi hai. Is it worth the risk of under construction for lower EMI? What's the real carpet area difference, anyone know?
