What I wish I knew about carpet area before upgrading in Greater Noida

Carpet area efficiency is often overlooked when comparing projects, especially with these super area calculations. I'm currently in a 2BHK in Sector 150 and thinking of upgrading to a 3BHK in Greater Noida. Ansal Orchid Bloom completed hai, but Drona Residency ongoing hai. Already have a home loan, so trying to justify the jump. Kya kisi ko Ansal Orchid Bloom ka real carpet area ka idea hai? Drona Residency ka builder trust factor kaisa hai, will they deliver on time? Which one looks better for 5-year appreciation, considering the price difference?
