Noida: Which builder offers better after-sales service?

Hi guys, I'm looking to buy a flat in Noida. I've shortlisted a few builders like Godrej Properties and ATS. Mujhe advice chahiye regarding their after-sales service. Has anyone experienced their maintenance? Which one is better in terms of complaint resolution and responsiveness? Kya aap logon ko pata hai, Godrej ka customer service kaisa hai after possession? Also, I'm curious about the quality of construction. Has anyone faced issues with durability in their projects? Which builder provides better warranty and quality assurance policies? I want to know which builder offers better peace of mind after handing over the property. What do you think? Any suggestions?
