I personally found looking at the visual design of the passport covers to be much more interesting than the 'power ranking'. It would be interesting to know what each passport image depicts or represents. I really like Sweden's passport cover. Maybe it's partly because the passport image isn't centred that makes it a bit less stuffy and official. Others I liked: UK, Malta, Mauritius - all old-fashioned but still quite nice. In fact, all of the passports look old-fashioned with their historic emblems (although El Salvador has an outline of the country, rather than an emblem). The Swiss one is the only one that looks modern in this regard.
