As someone that's lived in the US and Sweden, in my experience the US Postal Service is the only US government agency that's better than its Swedish counterpart.

USPS runs tens of thousands of post offices staffed by its own workers, while PostNord has privatized its retail services and makes you mail stuff from gas stations and tobacco shops. USPS delivers mail AND packages to your home six days a week, while PostNord only delivers mail 2-3 days a week and makes you pick up your packages from their partner businesses. USPS offers "Informed Delivery" as a free service that emails you every morning with scanned images of the mail you'll be receiving later in the day. You can renew your passport through USPS and they also offer some financial services.
