Is RG Mirage's premium justified for families?

The advertised price per sqft is always a marketing trick, it's never the final number. I'm looking at RG Mirage Tower M for a 3BHK, but the final cost after PLC, stamp duty, it's just insane, crosses 3.5 Cr easily. JC Studio Apartments, on the other hand, seems like a decent ready-to-move option at 28.90L. For rental yield, JC might be better given the lower entry point. But usable carpet area for a studio vs a proper 3BHK is a huge difference. Kya lagta hai, for a family, RG Mirage ka total cost justify hoga?
