I would vote the Netherlands... they even have a "kinder site" for children... so cute!
the only downsize, we don't get daily journals of the royals.
the one who did that (as i'm aware) are spanish, swedish, and probably belgian.
I think the UK and Danish ones are the best. The new Swedish one is beautiful, except for the fact that they've taken off the monograms of each member of the royal family, and the Netherlands one is nice too. The rest are pretty shabby and desperately need a revamp.
