Godrej Nest's premium justifies peace of mind

₹3.78 Cr for an under-construction 3BHK in RG Mirage feels like a huge gamble. I'm currently in a 2BHK and planning to upgrade, but builder delays have me seriously worried about UC projects, honestly not sure if I should risk it. Godrej Nest is completed, but is its premium worth it for future appreciation? Builder ka track record bhi matter karta hai. What's your take on these options for a 5-year investment horizon?
