My Parsvnath flat: Super area confusion and investment doubts

Sector 122, Greater Noida West – just moved into my Parsvnath flat last month, possession was in March. Honestly, the 'super area' game builders play is something else. My 3BHK felt way smaller than the quoted 1600 sqft, carpet area hardly 1000. It felt like I paid for a lot of thin air, making the effective per sqft rate much higher than advertised. Is this common practice ya I just got unlucky? I'm thinking of another investment now, maybe a smaller 2BHK. Builders like Parsvnath quote these crazy PLC and floor rise premiums. For an investor, is that even worth paying? Matlab, does it really give better ROI down the line? Or should I just look at secondary market deals? Suna hai wahan better negotiation scope hota hai. Any first-hand experiences on this?
