First home, big confusion in Noida Extension

Kya Godrej, ATS ya Gaursons ke projects mein actual construction quality brochure jaisi hi hoti hai? Sector 150 mein dekh raha hoon. Builders jo amenities dikhate hain, woh sach mein banate hain ya bas marketing hype hai Noida Extension mein? Suna hai finishing issues aur leakage problems bhi aate hain possession ke baad. First property hai, toh thoda nervous hoon, kaunsa builder better hai long term ke liye?
