I post in the voice of Christopher Walken
Everything she has done has been backstory stuff. She doesn't actively do anything interesting that isn't motivated by her need for love. How is she a better political leader? Yes, the people like her, but she also has a much smaller population to deal with and far fewer active threats than Azalin does.
Seriously: what makes her a better political leader or Dark Lord?
She is a better dark lord Both are terrible political leaders. But she is a better dark lord because she has more pathos, she is more tragic, her cruelty makes more sense, and her domain is so atmospheric and interesting for adventuring in. She is a much better fit for the gothic horror theme, than Azalin or Darkon. Most dark lords are terrible political leaders. I would much rather come up with adventures about Jacqueline Renier, and plots that stem from her sense of rejection and resentment, and a desire for love, than I would about Azalin's desire to escape Ravenloft. I said a while back, I am not a fan of Darkon or Azalin.
And she is much more than just about love. She and her family fled persecution in Falkovnia. She was trained by her father, the original lord of the domain, and she killed him to take power (again not a passive character at all, and nothing about that is centered on love or a desire for a baby). Importantly, and possibly why she is a better lord than Azalin, the population size increased after she took control (it seems because she took in refugees from other domains). But her domain isn't like Darkon. And her personality, cruel, manipulative and domineering (again not passive) are very good fits for a villain in a horror setting. Like I said, this was a character I could easily run, because she popped off the page and I instantly understood how to play her as an over the top villain. Azalin on the other hand, I never got. Also, I love lycanthropes. I think domain lords like her and Harkon Lukas are just fun to play and interesting. Also the idea of this underpopulated city, with abandoned homes and structures, socialites and a terrifying system of sewers (presumably infested by rats and were rats) really worked well as a site for adventure. It can handle mysteries, the occasional delve into the sewers and countless other types of adventures (a monster hunt in Richemulot is quite fun to run and play). And visually a city like Pont-a-Museau always seemed very well done (just in terms of the layout). Plus she has a twin sister waiting in the wings to seize power herself (which as a plot device for a GM is priceless). She is up there with Harkon Lukas and his daughter to me in that respect.
In terms of population size. That doesn't really matter. Richemulot works as an atmospheric domain because it has an abandoned feel where the city is underpopulated. Some of the best domains are small and have small populations (Kartakass, Barovia, Lamordia, Tepest, Forlorn, etc). It is a worthy domain of a good and well made lord. Darkon is just typical D&D fantasy with a veneer of horror (IMO)
