I will try to answer your "original" question in a roundabout way by stating that the period after the Napoleonic wars was "healthier" for France in diplomatic terms. This was true even though France lost back essentially all the territory she gained after the French Revolution.
From at least the time of Louis XIV (if not XIII) until the time of Napoleon, France was seen as the aggressor nation that others feared, and "ganged up" against. Napoleon (I) was basically seen as the last of the "aggressive" French rulers. After him, France followed a much more defensive foreign policy that earned her greater sympathy and respect from her neighbors.
After the end of the Napoleonic wars, France joined the Concert of Europe and became a peace-keeping force in Europe for the next few decades.
For instance, France joined Britain and other European countries in helping the Greeks during their war of independence against Turkey in 1830. Later, France was one of the 1839 signatories to the Treaty of London regarding Belgium neutrality.
France joined Britain and Piedmont in defending Turkey against Russia during the Crimean War. Napoleon III was also the "champion" (after a fashion) of an expanding Piedmont, and hence, Italian unification. That's because he preferred a weak but united Italy as a buffer zone against powers further to the east, rather than trying to have France divide Italy with other foreign powers, like his predecessors.
Around the turn of the 19th and 20th centuries, France joined the Triple Entente with Britain and Russia against a rising German-led aggressive tide that would shortly violate the Belgian neutrality of 1839.

For the most part, France lost all of her Napoleanic territorial gains at the end.
By the terms of the Treaty of Paris, concluded after the Hundred Days, France was reduced to her pre-revolution 1790 borders, with the exception of a couple of tiny enclaves surrounded by French territory that they were still allowed to keep.
They had been allowed to keep a bit more prior to the 100 Days, but the rest was removed as punishment for allowing Napoleon back into leadership.
