Gayatri Vatika vs SS Sainik Farms: Confused first-time buyer!

Fed up of renting, landlord raised rent AGAIN! Finally taking the plunge in Noida. I'm looking at Gayatri Vatika and SS Sainik Farms. Gayatri Vatika is cheaper, around 25L, but it's already completed. SS Sainik Farms is like 75L! Big difference, right? Is it worth paying that much more just for ready-to-move? I'm thinking about resale value bhi. Which one will actually give better ROI in 5 years? Honestly not sure if location matters that much between the two for rental potential. Also, anyone living in either? What are the real maintenance charges? Brochure mein toh kuch aur hi dikhate hain! Any advice?
