sarleon faction is best for me. King Ulric is belligerent but courageous and an excellent leader.
It's easy to make friends with this faction and get lands. In addition, this faction is often at war.

I find the Ravenstern faction too closed in on itself. King Gregory is a blunderer, which is funny, but he's very good friend with Ivanus who does a lot of banquets, so it's hard to get something. These people are very worldly.

The fiervains are valiant, a little wild. They are very open but also difficult to get something from them. They are conquerors and fearless.

To be a good d'shar you have to choose to be born of a tribal chief father to be at war naturally with the inquisition and to be able to really help these people. Devastica will not hesitate to chase after you all over the map to beat you up, great fun! The d'shar conquerors are sometimes powerful, sometimes fragile depending on the game. Bahadur Khan is majestic during battles, but again, hard to get land.

The empire is the faction where you are most poorly received. You are made to understand that you have no place in this faction. Marius is neutral with you like all kings, but the vassals don't consider you at first.
The units are very nice and well armed against snakes and noldors.

This is how I felt each faction and it is that of sarleon that I like.

Fierdsvain is so much fun for me. Love me some heavy shock infantry combat.

empire. roman larpers and best roster. knights train super fast, legionnaires are strong and easy to train and the armored crossbowmen are op af.
