Which would be the best house on the throne?

Like the title says, which house would be best on the throne? In a scenario where we can’t choose neither.

Personally I think the Tarlys and Tyrells are good options.

Because obviously (almost) every house has some people that would be great leaders, and where in some cases.

But looking at the history, not only peace, but leadership skill, ambition, smartness and things like that: which house would be the best to have on the throne?
