New projects' build quality is just a gamble, right?

MVN Aero One — I'm seriously looking at it but feeling a bit hesitant. Currently in a 2BHK in Sector 57, thinking of upgrading to a 3BHK there. My biggest worry is construction quality. People say new builds have issues after a year, like cracks or seepage. Also, are the promised amenities actually delivered at possession, or do they just tick boxes? Is the price jump worth it for the actual day-to-day living experience? How are the maintenance charges compared to service quality? Would love to hear real experiences from residents.
