Greater Noida: How do you really check society RWA before buying?

Been looking for 8 months now and it's getting exhausting. Kids have moved out, so we don't need such a big place anymore. I'm weighing options between ATS Pious Hideaways (under-construction) and Shatabdi Rail Vihar (completed). For Shatabdi, I've been trying to figure out how to *really* assess the RWA and actual amenity usage, not just what brokers say. My hack is spending an hour or two just sitting in the society's common area... watching who uses what, how the guards behave, if maintenance staff are visible. Anyone else have similar ways to check RWA quality and practical amenities before committing? Hope this helps someone.
