Super area is a total scam in Noida projects

My landlord just increased rent again, so I'm finally taking the plunge and looking for my own place in Noida. Fed up of renting yaar. I'm checking out some 2BHKs around Sector 145, maybe even Yamuna Expressway side, considering the Jewar Airport buzz. Builders like Airwil Group are showing me their plans, but I'm super confused with this super area vs carpet area thing. Matlab, they're showing me a 1200 sqft flat, but carpet area is barely 750-800. Is this normal? It feels like a big trap, they're charging me for space I don't even get. Also, payment plans mein construction-linked best hai ya down payment? Kon sa option zyada safe hai? Kya broker ismein help kar sakta hai ya direct builder se baat karna better hai? Any experiences?
