I think that to say you is most ideal, you must think which familt you would most want to be a part of. If you do that then, you think that family is most ideal.
For me it's the Grimaldi's - hard working, normal because of their scandals and not in spite of them ands really beautiful and glamourous.
But, then there's Norway, a close family who isn't arrogant or conceited enough to dislike Mette-Marit on first appearance. They saw her for who she is and didn't judge her. And Martha-Louise is so down-to-earth - a great sister-in-law to have!
Denmark for their ability to move with the times, although Noway seems to be doing that a little more successfully at the moment, but adding CP Mary to the family certainly helped the Danish RF.
Sweden is always, underneath it all, respectable and stabele. I don't think they've had any serious scandals - at least not any that have lasted.
The Netherlands - Maxima (and Claus before her) marrying into the family proved that the Royal Family is open minded and accepting enough to see beyond a person or their family's mistakes and see that person for who he/she is now. I really respect Queen Beatrix, the Dutch RF and the Dutch people for seeing Maxima for who she is and not judging her for her father's mistakes.
Belgium - Because I love Mathilde! The love between her and Phillipe is just so beautiful to see and they have 3 beautiful children to add to and strengthen their love.
I admit that I don't know much about the Spanish RF, but I do respect King Juan Carlos for bringing democracy back to his country.
