I thought a lot before answering. Because, well, in both of them, you're not free. A totalitarian government is at least more honest in this point: everyone knows that in a dictatorship, you don't have freedom of speech, or freedom of ideology. In democracy, most part of the people think they're free, but they are imprisoned by the taxes, the laws, and whatever. Although you can (theoretically) speak what you think in a democracy, this don't really change the way the things are. And if the government does hear you and make some changes, well, probably it was not in name of democracy, but to show you how you live in a democratic country and you're respected as a citizen.
Whatever, I'd prefer the democracy anyway. In a dictatorship, if the government does something wrong, and you complain about, and make a rally about it or something, they'll probably shoot or arrest you, while in democracy, you're supposed to not be arrested or get some kicks in the face when you're complaining about something. So, if they does arrest you or anything like that, they're proving they they are no more a democracy.
Well, just to end this post before I get any other ideas, yes, a corrupt democracy is prefered, but, just if REALLY is a democracy, not the Venezuela kind of democracy.
