Militarily Europe walked away with simple caricatures of the war, but the lionization of Ulysses S. Grant. Grant was (rightly) recognized as a new kind of general - one that would be far more familiar in World War I than in the Napoleonic War. This led to a lot of fame.
Generally, the US revolutionary war was viewed very positively in parts of Europe. That upstart new world was finally in its place and would now tear itself to pieces without European governance. Britain considered entering the war early on(on the southern side!) and benefited from the economic collapse of the Americas. The British commercial fleets went from near-parity with the US merchant marine to unquestioned ruler of the commercial seas by the devastation of the blockades and the lack of insurance underwriting for north or south flagged vehicles.
But a lot of things were missed millitary that they would learn in 1914. The role of rail lines and junctions, and the early signs of trench warfare and total war were the only thing that could break near-industrial societies. The potential of armored battleships and submarines. (Though to be fair, imagine how much history would have changed if the Turtle had detonated its torpedo in the Revolutionary War!) These lessons would be learned a hard way sixty years later.
