What is the most successful hedge fund in the US?

Can you elaborate on the criteria used to determine the most successful hedge fund in the United States? Are we looking at the largest asset base, highest returns, or perhaps a combination of both? Additionally, how does one measure the success of a hedge fund beyond just financial performance, such as its impact on the market or its ability to weather economic downturns? Is there a particular fund that stands out as the most successful in recent years, and if so, what are the key factors that have contributed to its success?
