Passport “strength” is a pretty nonsense metric except from nations with strong restriction on their people’s travel, like say if you’re on an Afghan passport.
When you see these listicles they are basically just gibberish clickbait farm postings. Don’t pay any attention to them. There really isn’t “strongest” passports. What they measure is mostly nonsense that almost all passports from most developed nations are about the same
It’s the bottom of the list that is important, not the top, but those countries don’t make headlines and don’t have high value consumers surfing the internet looking at articles in English.
