Noida Extension or Sector 9 for first home?

₹65 lakh is my budget. I'm looking at 2BHK flats. Noida Extension seems cheaper, but Sector 9 is closer to my office. My parents keep saying Sector 9 is better, but Noida Extension mein, you get more space. Honestly, not sure what to do. SM Homes has projects in both areas. Is OC important enough to pick Sector 9? Noida Extension ka ROI kaisa hai? Ab samajh nahi aa raha.
