The US is a bit biased by considering its revolution a great success - which it was, for the white population. There was never a wholesale slave revolt, but the revolt of the slaveowners was successfully suppressed.

Conversely the UK never had a popular revolution and transitioned to constitutional monarchy (eg also Sweden).

France was very bad in the medium term; the Terror, subsequent invasion, Napoleon etc. Perhaps only a fully free society at the 5eme republic.

Much of the world by sheer number of countries got its freedom either at the end of WW2 or the Cold War.

Cuba and Haiti are still going badly.
