A new report from a top OECD education expert has a table on the top 20 universities in the world. Seventeen are in the U.S.
The list may be skewed because it was originally constructed by a Chinese university (how did Seattle get on the list??). Nevertheless, it suggests something about global reputations.
The report also says that "France and Germany...are no longer among the world's leaders in developing knowledge and skills." Incidentally, the author is also the project director for the OECD Programme for International Student Assessment, so he is quite knowledgeable.
