Upgrading to Mahagun Marvella — is the premium worth it?

Did a site visit to Mahagun Marvella this weekend and honestly, it felt a bit overwhelming. I'm currently in a 2BHK in Sector 120 and thinking of upgrading to a bigger 3BHK. The price range is quite high, and I'm wondering if the premium for a completed project is truly justified for daily living. Is it genuinely a good home, or just good on paper? I'm keen to know about the society and community vibe there. Is it friendly, or do people mostly keep to themselves? Also, how's the neighborhood quality? Are good schools, hospitals, and markets really close by, or is it a bit of a trek? Already have a home loan, so trying to make a smart move here. Any current residents or recent buyers have insights on the actual livability and the real cost of living there?
