Might be ridiculous, might not. French general universities are cookie cutter, they're al meant to be more or less equivalent. The Grande Écoles focus on one specific subject, so they get hammered on rankings, but they are all excellent in their fields. There are no great German universities, full stop, for the same reason as in France, and tehy don't have a GE equivalent. There are some departments in some universities that are world class, Karlsruhe in CS, Saarbrucken in Computational Linguistics.
