There's (almost) no FTTH in Germany. The US used to be as bad as Germany, but it has improved significantly and is actually pretty decent these days (though connection speed is unevenly distributed).
Both countries are behind e.g. Sweden or Russia, but Germany by a much larger margin.
There's some trickery done in official statistics (e.g. by factoring in private connections that are unavailable to consumers) to make this seem better than it is, but ask anyone who lives there and you'll be surprised.
