Since there are so many Links, i am just going to compare Kratos to twilight princess Link.
I am sorry but Link is not really that big of a fighter, he is more like Indiana Jones, he gets into a fight here and there but most of the time he is avoiding traps and solving puzzles.
Kratos even before getting magic was a spartan, so he is a well trained warrior. Also, he has very powerful magic at his disposal, while Link can only transform into a wolf. Even with Link's ranged attacks, Kratos has items to deflect them and he has magical ranged attacks. Not to mention that his dual swords have a huge range.
