Which was better? Which led to better developments? Which led to a better governing philosophy?
This is essentially a very old debate that is still going on. In a nutshell, this argument began with Edmund Burke and Thomas Paine. The latter thought the two revolutions were both good. The former wrote a big book criticizing the French Revolution. The latter then wrote a book criticizing the criticism with a much better sounding title (but overall, not that great of a book.)
Due to the time period, the largest and most destructive debate of the last 500 years hadn't really begun yet. That was the debate which began with the theories of Adam Smith and Karl Marx. It had not yet really become a debate yet. This would happen when the Constitution was being debated and would continue until it's official settlement in the early 1990's.
(I think it's pretty obvious where I stand on this one.)
