Who all do you think are the strongest character in each book you’ve read?

So, I just finished with HS2 and I was just wondering who was the strongest out of the main characters. I mean There are the Horsemen among them but then there’s also Malbonte. But among them even though Malbonte killed Death I still am not sure who among them is the strongest.

Also I think MC of arcanum is the strong as >! She is the tarot master !< then there’s of course the MC from LOW
