Noida property mein carpet area ka game kitna real hai?

Okay I'll be honest — I'm confused about carpet area. AKS Rose 4 looks good, but it's Greater Noida. Metropark Shaurya Apartments is ready, but is it cramped? My wife's priority is space for the kids. Has anyone compared the actual usable area in both? Builder promises toh sab karte hain. And is the OC mil gaya or not? Should I focus on possession status over location? Need at least a 3BHK. What's the real story?
