They are still copies of each other as far as I know.
It is not like a specific lord is honored so they raid less, or a ruler is peaceful that favors peace time over wartime.
Haven't noticed anything for battles either.
For dialogue, I believe recently they added that npcs now recognize the player if he is the ruler, but other than that, there are extremely low amount of dialogue options compared to Warband that it is not worth spending time into experiencing them before full release.
