Ready to move is the ONLY way to go in Noida now. Agree?

Kids have moved out, so I'm selling my big house. Looking at Mangalya Novena Green and JMDR Arihant Green. Novena is pricier, but ready. Arihant is completed too, but tbh, the maintenance charges seem high after talking to residents. Which is the better long-term society? What does the community think?
