Noida Ext: Post-possession reality, confused about quality.

Moved into my Godrej flat in Sector 150 last month. Construction quality se thodi tension hai, abhi se minor cracks dikh rahe hain. Mera dost ATS ke project mein hai, uski bhi similar issues hain. Post-possession maintenance charges bhi kaafi high lag rahe. Kya Gaursons ya ACE ki quality aur maintenance better hai? What's your ground-level experience?
