Selling bada ghar, downsizing in Noida – need help!

Kids have moved out, so I'm selling our big house. Looking at smaller flats in Noida now. Shivkala Apartment and Supertech Renesa are on my list. Honestly not sure which one's better for older people. Heard Supertech projects can be risky with possession delays – anyone faced that? Shivkala looks safer, but is it worth the price? I'm also thinking about resale value later on. Which one would be easier to sell if I ever need to? Also, hospital proximity is important. Does anyone know which society is closer to a good hospital? Maintenance charges bhi matter karte hain. Koi idea hai which is more reasonable? Hope someone can give some insight.
