Arcueid route is so simple and mostly boring, Ciel's route was actually good(IF WE EXCLUDE THE FACT THAT HALF OF IT IS ARCUEID'S ROUTE), but i don't really care about the history and i hate Shiki, they say the far side is the peak part, but i'm not really interested enough to look after it(for now).
Arcueide route: 3.0
Ciel route: 7.5
