Is Noida Extension a good option for first-time buyers?

Fed up of renting, landlord raised rent again! Finally taking the plunge and buying something. I'm torn between Noida Extension and Sector 156. Noida Extension mein, Omaxe has some affordable options, but I'm worried about future appreciation. Sector 156 seems premium, maybe better ROI long term? Honestly not sure if I can stretch my budget that much. EMI vs rent math is killing me! Also, under-construction vs ready-to-move is a big headache. So many RERA stories out there. Which would you pick if you were in my position? What does the community think? Vote below!
