This is a pretty dishonest way to present this IMO.
I've been traveling for the last 10 years and my American Passport never got in my way, and in exceptionally few cases would anything have been any easier with the passport from the #1 country on the list. Yes a few times I had to fill out some extra paperwork.
America has a VERY STRONG passport. This is a bimodal distribution where most of the passports in each of the groups are equivalent to each other and the US is in group A.
It seems like this is hugely effected by covid ban right now. A large % of countries that are just enter - italy as an example - are counted as Red given the covid ban.
