Noida Extension builder quality is just hype

Honestly, buying in Noida Extension is tougher than I thought. Even for me, in real estate. Godrej, ATS, Gaursons ka construction quality, like plaster cracks aur seepage, kaisa hai? Jo amenities promise ki, woh milte bhi hain ya sirf brochure mein? Post-possession maintenance charges ka kya scene hai?
