I think I'll rather be under French rule than Prussian. Prussia's War of Liberation was more about 'liberating' as much of Germany as they could get their hands on and keeping Austria out. The smaller German states allied themselves with France in the first place (Bavaria, Wurttemberg, Baden, and Hesse-Darmstadt especially) so that they would not be ingested by either Austria or Prussia.

The Belgians in 1815 thought that the Prussians were worse than the Cossacks of the year before. And no one could predict the evil that came out of Germany in the 20th century-twice.
