Assassin per Apocrypha. When you remove plot armor from the board, Assassin becomes the de facto best servant.
The reason they were forced to summon Jack and Semiramis is because in the Apo Worldline, Assassins went meta and kickstarted an era of victories that made them the most dangerous class possible. They were killing masters left and right and even servants too by ambushing them while vulnerable or mid-battle.
They also have low cost so they can actually fight properly unlike super strong heroes that get cripples or can use their NP once (like Artoria's whole issue in FSN)
But since the amount of Hassans is limited, they all got their characteristics exposed and people started HGWs with countermeasures for every single Hassan straight away.

If you can actually afford a catalyst, I'd assume Chiron is one of the safest Archers possible. He can use Territory Creation, Presence Concealment and hold his own in a fight melee. He isn't flashy but should be able to self-sustain and elaborate strategies to win along the way.

Assassin has the most wins in the Apocrypha verse, you know the timeline where a HGW happens every other month.
