Im torn between these 3 crews honestly but i would prefer most of the time the mob of the dead crew.
I always liked mafia movies and series (the godfather, good fellas, the sopranos, etc) so i feel kinda bias with the mob crew
The call of the dead crew was also a very pleasant surprise back in the day, having a celebrity cast for the first time was very cool, also including George A Romero to the map was a excellent idea
The victis crew at first felt rough and inusual but i started to like them in die rise, specially russman, they had fun interactions and had some good quotes.
