If we look at the history some countries got maximum development in Dictator ship while some got maximum development in democratic government. Every system has it's own flaws and benefits. What do you like ? if we talk about the welfare of general people.
If and only if the leader is great, I'd pick dictatorship. If the masses are well educated and informed then democracy. I mean both forms of government is good and what i just mentioned are their flaws abd downfalls. But weakness and pitfalls aside, I'd pick democracy. At least if i bitch about something, i could tell and voice my ideas freely.
