Builder choices for a peaceful life in Greater Noida

Visited some projects in Greater Noida West last weekend. Kids moved out, so selling our big house for a compact 2BHK/3BHK near a hospital. Godrej, ATS, aur Gaursons ke projects dekhe hain. Honestly, delivery track record kaisa hai inka? I'm worried about construction quality issues after a few years. Post-possession society maintenance kitna accha rehta hai? It's important for a peaceful life. Any real experiences with these builders?
