I prefer the Danish and Spanish models because they are actually integrated into society, transparent, and humbler. Figures like Mary and Letizia have a clear work ethic, Letizia, in particular, brought her background as a journalist into her role, which actually makes a difference. These women treat their roles like a job that requires substance. When you compare that to the BRF, the difference is embarrassing. Most importantly, there isn't this constant, sordid history of enabling pedophiles, lack of transparency or shielding shady connections. And there's no extreme laziness or preciouness in them. That’s why the British royals stick out so negatively; they lack that professional substance and accountability. I don't think constitutional monarchy is the ideal system, but I also think there's worst systems around; the issue is that this is simply not working in UK because it's rotten to the core.
Also my opinion in their in laws like Felipe sisters and his father is more negative, and this points the contradictions of monarchy. I won't enter in details here as it's not the issue of this topic, anyway.
