Is a ready-to-move premium worth it for families?

Gurgaon keeps coming up every time I shortlist something for our family upgrade. We're currently in a 2BHK and honestly need a 3BHK for the kids. I've been looking at Signature Orchard Avenue 2. It's under-construction, which makes me a bit nervous about delays, especially with kids' school admissions coming up. My wife's priority is a safe neighborhood and good schools nearby. Adani Aangan is another one on our list, it's ready-to-move which is a huge plus, but the price difference is significant. Is the premium for immediate possession and established social infra around Adani Aangan really worth it? For a 5-year outlook, which project do you think would offer better appreciation? Not sure if the ongoing project's lower entry point makes it a better bet long-term. Has anyone done site visits for both and seen differences in actual carpet area or amenities? Just trying to figure out the best move for us.
