Greater Noida mein builder experience aur maintenance charges?

My big house finally sold last month, and now I'm looking for something smaller in Greater Noida, around Pari Chowk ya Noida Extension. Kids have moved out, so don't need such a big place anymore. Thinking 2BHK ya compact 3BHK, budget around ₹90L-₹1.2Cr. I'm considering ATS, Godrej Properties, and Gaurs Group, but honestly, not sure which one. Main concern hai construction quality, yaar. Bohut stories suni hain seepage ki, ya finishing issues ki after possession. Is it worth paying a premium for ATS ya Godrej ki quality? Aur post-possession maintenance charges ka kya scene hai? Kuch builders toh baad mein bahut badha dete hain. Koi bata sakta hai in projects mein actual quality kaisi hai, aur maintenance ka experience kaisa raha? Near hospital connectivity bhi important hai.
