For me both have great advantage. But the difference is tha Investing is putting your money on stake. In saving you can control your money without earning profit
Gold can be the one option to invest and there are assured returns in it but you to have patience as the prices of gold fluctuates everyday and so far real estate is concerned you need huge amount to invest in it as the land prices are climbing up and up so for an average person its not possible to invest in property or land.
