Yes, who could be better? The Chinese? Russians? Sweden? lmaooooo
Sweden is better.
If by greatest, the OP means economic and military might, then the US is objectively the greatest.
However, the US isn’t the best, and I place a lot of weight on human rights. There are countries that respect human rights more than the US, especially Canada and the Nordic nations.
idk man, between the USA and those Nordic countries I'd much rather live in the US. From what I hear on the internet from people who live in those countries, it's really difficult to get ur mf ca$$$h up due to taxes and sh**t.
