Is Mahagun Mywoods quality actually good long-term?

Visited Mahagun Mywoods Phase 3 last weekend, looking for a 3BHK for my growing family. Honestly, under-construction projects mein construction quality ka bahut doubt hota hai. Everyone glorifies amenities, but nobody talks about the cracks and seepage after 2-3 years. My wife's main priority hai ki kids ke liye play area safe ho, not just a ticked-off checkbox. Also, maintenance charges ka kya scene hai? Builders bas charge karte hain, par service quality zero. Is it worth paying so much for just a fancy clubhouse that's never used? Disagree? Tell me why.
