Should I? Would I?
Marengo makes a point here. We shy quiet Belgians do not necessarily feel better than the Dutch (unlike the other way around

), but we like to think our educational system is better, and, ok, so spacial planning is a mess... we don't like uniformity, so what's the deal? They laugh at our bad roads, and we wonder why their windows all have to open outward... Oh, wait, because the houses are so much smaller...
But, let's move on from the subject of Dutch vs Belgian (that issue has been solved to both of our satisfaction almost 180 years ago, despite some delusional ideas circulating these days)
I think that's only natural, the same is probably true for the Scandinavian royals amongst each other.
Both princesses have their own character and characteristics, and both are perfect for their respective countries, and neither would "work" in the other country. Mathilde would be too "soft" for the Dutch, too boring, whereas Maxima would be too outgoing, too "eye-catching" for us modest Belgians.
So basically both Princes made a perfect choice.
