Who had the best claim?

Harold Godwinson was crowned King of England when King Edward died in 1066. But two important people wanted the crown of England. They were Duke William of Normandy and Harald Hadrada , King of Norway. This led to two major battles, which were the Battle of Stromford Bridge and the Battle of Hastings. In the Battle of Stromford Bridge, Harald Hadrada died.  Harold Godwinson was killed in the Battle of Hastings. In the end, Duke William of Normandy became the King of England. In my opinion, Harold Godwinson should have had the best claim to the throne since the past king, King Edward, chose him and the nobles crowned him.  But William made Harold take an oath promising him to help become the king when Harold was captured when he went for a visit to Normandy in 1064. William accused Harold of being an oath-breaker. But Harold only went for a visit and he didn't threaten or harm anyone. William used his connection with King Edward and convinced many people that the King had promised the throne to him.  Harald Harada, King of Norway wanted to be the king as one of his ancestors, King Cnut, had once ruled England, and Hadrada thought it was his turn to be king.   Harold’s brother Tostig wanted revenge against his brother. Hadrada used him to fight against Harold.  Both, Duke William of Normandy and King Harald Hadrada of Norway used violence to fight for the throne but Harold Godwinson did not. So I think he had the best claim to the throne.
