Noida investment: My 2BHK/3BHK confusion

Honestly, even though I'm in real estate, buying my own place in Noida is a whole different ball game. I'm looking at a 2BHK vs 3BHK for investment, and honestly, not sure which way to lean. My budget is around ₹70-80L. For this range, should I push for a compact 3BHK in Noida Extension ya stick to a well-located 2BHK near Pari Chowk? Matlab, future appreciation kiska better hoga with all the upcoming infra? I'm thinking about the Jewar Airport and Aqua Line impact. Will 2BHKs near these new infra developments see better rental yield, ya 3BHKs for families? Builders like ATS or Gaurs ke projects mein, what's the ground reality for these configurations? I know what they tell us, but public ka kya opinion hai for long-term growth? Koi specific projects ya sectors people recommend? Any hidden charges I should be extra careful about?
