Noida Extension: Gaurs The Islands ka premium worth it?

The premium for new projects in Noida Extension feels a bit much these days. I'm currently in a 2BHK and thinking of upgrading to a 3BHK ya maybe even a villa. Already home loan hai. Gaurs The Islands ka price ₹10 Cr+ hai, feels like a huge jump. Deepak Green Residency jo completed hai, usmein investment better rahega kya for 5-year appreciation? Ya Gaurs mein is that premium justified?
