Hilston by Urbtech vs Arihant Green - which one?

Kids have moved out, so don't need such a big place anymore. Thinking of something manageable in Noida. Hilston by Urbtech is ready to move, which is a big plus. But Arihant Green is completed too, and maybe the society is more settled? Carpet area efficiency matters a lot to me. Honestly not sure which one offers better usable space. Price difference bhi hai, obviously. Koi batao, which is better for resale later?
