My 2BHK upgrade path — honestly feeling stuck

Almost 70% price jump for a 3BHK from my current 2BHK in Knowledge Park 3 feels like a lot. I'm eyeing Pari Chowk or a villa near Yamuna Expressway. Is this 3BHK premium truly justified? Considering Jewar Airport, will 2BHKs or 3BHKs appreciate more? Or is 2BHK better for rental yield in Greater Noida?
