My Noida Extension home hunt: Builder delivery & quality?

Kya Godrej Properties aur ATS ka delivery track record Noida Extension mein sahi hai? I'm finally taking the plunge, fed up of renting. Looking for a 2BHK around ₹80L in Sector 150. Both builders have projects there. Main concern hai on-time possession aur construction quality. Kya inke projects mein baad mein seepage ya finishing issues aate hain? Customer support after booking bhi matter karta hai, honestly. Any real experiences with these two? Ya koi aur builder jaise Mahagun ka experience better hai for end-users?
