Depending on what you're doing, everything you've listed can be a good process. Best Method for what? What exactly did you have in mind?

One exception would be adding sodium chloride to HCL. Not sure what that would be good for, and no, it will not disolve gold. At least not without some form of oxygenation.

hello goldenking , aqua regia ( HCL,HNO3) is a faster method it can dissolve large metals than other and it is commercial method it has more fumes . SO2 gas is good precipitant but difficult to handle and achievement , smb is also good precipitant when we dissolve smb in acid it generate SO2 bubbles this SO2 bubbles precipitate the gold.
Hydroquinone is a storm precipitant please see this link .
