AKS Rose 4, Sarthak Homes — which has better resale?

Kids have moved out, so don't need such a big place anymore. I'm looking at smaller apartments, maybe around Noida. Resale of my existing property is key. I'm seeing AKS Rose 4 in Greater Noida, but it's still under construction. Honestly not sure if I want the headache. Sarthak Homes is ready, but is the resale value actually good? I heard the carpet area in AKS is a bit better for the price. I'm also thinking about the amenities; will I even use a gym at this age? Hospital proximity matters more. Anyone have experience with resale in Sarthak Homes? Is it worth it, or should I gamble on AKS Rose 4 appreciating in value? What's the actual resale market like there?
