Who Had The Best Claim?

In 1066, three men hoped to become King of England after Edward the Confessor died. These three people were Duke William of Normandy, Harold Godwinson, the Earl of Wessex and Harald Hardrada, the King of Norway. One of Duke William's claims to the throne was that he had the Pope voting for him to become king. In the olden days if you had the Pope on your side, it was one of the largest advantages you could have. While Harold Godwinson had the recommendation of the previous king, Edward, and Harald Hardrada had an ancestor, King Cnut, that was a former king of England. Out of these three men, I think that Duke William of Normandy had the best 'claim to fame' and in the end Harald Hardrada and Harold Godwinson were killed leaving William the Conquerer with the crown.
