I would say yes but only on average because revolutions are made by coalitions of opponents of the regime.
For example, the overthrow of the Shah was achieved through the combined forces of liberals, secular nationalists, conservative Islamists, communists, populist leftist Islamists, etc. Only for one group was it worth it. Likewise in Algeria (where the secular nationalists won), Russia (where the communists won the civil war, and secular nationalists are winning after the fall of communism), etc.
For the group that wins, the revolution can be considered worth it, but many will be disappointed.
Note that I am taking a more subjective approach to this issue than Eugine_Neir did. I think it is fair for an inefficient ramshackle dictatorship to consider their revolution a success if they get to spread their ideology.
