I voted for the Roman Empire, it's legacy created the Western world and it's power was arguably the greatest of any power in history, including the present day U.S.A. People flocked to be called Roman for centuries, their cultural dominance would have Coca Cola and McDonalds advertisers shaking in their boots and their army was the greatest fighting force on Earth for almost five hundred years.

I agree, Tolkien's Valinor truely is great.
