First-time buyer's reality check on Noida Extension

Okay I'll say what no one says, most builders in Noida Extension overpromise on amenities. CRC The Peridona mein jo brochure mein dikhate hain, woh real mein milta hai kya? Yaar, construction quality ka bhi darr hai. Cracks, seepage, fittings issues... kitna common hai? Should I trust these projects? Change my mind.
