Sasaki's skill was already said in the comment above, but he was basically so skilled that literally all Servants in the war didn't want to fight against this guy in a melee fight.

Hercules was still able to retain his fighting skill even in a state of madness, and since every Servant is basically based off their historical figues, Hercules is at least equal to, if not more skilled than his real life legend. For an in-canon example, he was able to fend off Gilgamesh and even surprise him. Gilgamesh being the strongest Servant in Fate and holding thousands upon thousands of hax, which you probably know (since he's pretty popular on the main wiki).

For another example, she was able to fend off Lancer (Cú Chulainn), who was able to fight Gilgamesh for half a day before being taken down, and is said to be able to take out Hercules (albeit he has a low chance of sucess). Lancer in his myth was also able to take on an entire army, and even his dead body was still able to harm people who even came close to it.

There's plenty more fights she's in though, and this isn't counting the fact that she also has the same experience her real life counterpart.
