European countries when it comes to historic sites. Rome alone has more to see than all of Germany put together. Not to mention that most of Germany is a total rebuild. The most visited castle in Germany is only 153 years old.
Germany has some interesting stuff, but after three years in Italy, I felt like I was barely starting to scratch the surface. After my first year or so in Germany, it was lather, rinse, repeat. Berlin is an awesome city - but it's not Paris, Rome, or London. And I would argue that Vienna can give it a run for its money.
Give me Italy, France, the UK any day when it comes to historical sites.
