First of all you cannot just compare them like this it has to be a one on one fight without the "Immortality" and then consider them to an equally known or unknown environment Wang Ling can travel a Lil more then the speed of light but Goku can travel 22.321 trillion MPH or 33,314 times the speed of light which is easy if they were face to face rather then far apart also in this scenario Goku needs bloodlust as of to kill wang ling with no "Immortality" in first punch or what he does if not wang might win but i still see this as win for goku
