Builder RWA control is the real post-possession nightmare

Just got possession of my 3BHK in Sector 65 with M3M last month, and honestly, the finishing quality is already a concern – small cracks showing up. I'm wondering if this is common with them or just bad luck. My friend in a Godrej project on Golf Course Ext Road says their RWA formation is a nightmare, still builder-controlled. Is this typical for Godrej? What's the maintenance like after 6 months? Seems like DLF projects manage RWA better. Anyone else seeing these issues with new societies?
