Noida Extension post-possession reality check: What's your experience?

Just moved in last month to my new 3BHK in Sector 137, Godrej project. Overall the flat looks good, but abhi se I'm noticing kuch minor finishing issues, like plaster cracks and some seepage signs in the bathroom. Also, the maintenance charges seem quite high for what we're getting. For those who bought from ATS ya Gaursons in Noida Extension, especially in Sectors 150 or 78, how has your construction quality held up after moving in? And are your maintenance charges reasonable? Share your first-hand experience, please. Kya ye sab common hai?
