Best Emperors / Rulers that make me want to high-five them

I've made a list of the "Worst Emperors / Rulers that make me want to flip the table" 

Now, I would like to give thanks to the Emperors/Empresses who make the heroes' task easier and our own task as drama-watchers less angst-induced. Even if some of them are the villains of the story, at least they are competent at their jobs and keep a cool head and a clear mind.
