Story wise it starts abysmally, basically mandating a demon playthrough so you can cull all those pathetic, degenerate NPCs that boss you around, but it gets better later, and chapter 4 was quite nice (the roating camera gimmick was cool there if I’m being honest). Still, Kingmaker was far ahead in this department. The central theme was not as intriguing as Kingmaker’s curses one, but maybe with different choices it shines more. Companions are on par with Kingmaker, with some stand out ones like Regill. Reactivity, especially along the mythic paths is great and miles ahead of anything in Kingmaker. And since mythic paths besides story offer gameplay variety, it makes it a very replayable game (if you can stomach going through some of the worst stretches again).

All in all, the character building is so good it makes it worth playing, but it is a step down from Kingmaker in almost every other way.
