We all know and understand the democratic system.
In theory multiple ideas are floated by charismatic politicians and the best idea wins. In practice? not so much.
The major benefit of democracy in my opinion is not the theoretical idea of people choosing their leaders, but that it allows an orderly transition of power.
People eventually get annoyed by their governments and often people close to power too long start to reek. Democracy allows those people to be replaced, probably by younger less reeking politicians with the same views, but sometimes with those with slightly different views.
Unless the outgoing government has been catastrophic, the replacements are rarely a radical departure from before.
