Post-possession reality: Which GNoida builder is truly reliable?

Just got possession of my 3BHK in Sector 150 last month, aur abhi bhi settle ho raha hoon. Jab site visits kar rahe the, ATS ka construction quality bahut sahi laga tha, but abhi thode plaster cracks dikh rahe hain already. Matlab, Godrej Properties ya Gaursons ke projects mein bhi aisa hota hai kya? My friend in a Mahagun project faced so many hidden charges at possession, like extra EDC/IDC jo pehle bataya nahi. Humare saath bhi thoda hua, not gonna lie. Aur customer support toh booking ke baad gayab hi ho jaata hai, calls pick nahi karte. Is it just my experience, ya sab builders ka yahi haal hai Greater Noida mein? Kya lagta hai, which builder truly delivers on quality and transparency post-booking? Thinking about future resale value with Jewar, so long-term experience matters.
