Noida Extension mein kis builder ki construction quality reliable hai?

Under-construction projects in Noida Extension are a gamble, period. Sab log Godrej Properties, ATS ka naam lete hain for quality, but I've heard mixed reviews, especially post-possession. Plaster cracks, seepage issues... I'm fed up of renting, landlord ne rent badha diya phir se, so finally taking the plunge. My EMI vs rent math says buy. But yaar, construction quality ka real scene kya hai for builders like Gaursons, ACE Group, Mahagun and M3M India? Koi batao, should I trust their promises? Change my mind.
