Apart from the night city mega event a couple of months ago FC are the only way to get KP. Overall KP seems like the best choice as he can use some of the best talismans and has the health to survive even after passive disable. While ferryman can prove useful in a lot of ways, it’s hard to fight against viper talismans with him. KP’s passive removes golden effects as well so is arguably better than ferryman in that respect as well.
