What defines best? If we are going on how good the country was to live in under them that is fine, but surely other factors control this. Maybe you should think about it like Pokemon or Top Trumps, points for hair, name, ability to kiss babies, amusing hobbies or quirks etc, and then total up the points It's the only fair way. I am not suggesting you do it on here that would be dull.
