I'm going to play in an Armageddon Crusade
Looking into the Crusade rules there's some serious power creep. Older factions have jack all in their control of what they can get. Custodes just roll on a chart for their extra win condition, then roll on a chart to see what extra rewards they get. Meanwhile the Codexes released this year have so much control in their options. Emp Children have full control on what drugs they make and have methods to gain ingredients to make sure they get what they want, 1k sons a billion options and paths while Chaos Knights have have full control on their level of influence from dark gods, their house hold and their vassals.
