I have often promoted the measure of least additional votes required  
to become a Condorcet winner as one understandable and natural/fair  
(and simple, easy to display) measure of which candidate is the best.  
This measure leads to the minmax(margins) method. The "least  
additional votes" approach minimizes the strength of opposition to  
change the winner to any single alternative winner after the election  
(and thereby aims at making the society more stable).

Not all on this list agree that minmax(margins) is a good method. It  
may in some extreme cases elect outside the Smith set. But in such  
cases the defeats within the Smith set are stronger than defeats of  
the winner outside the Smith set, so electing that candidate would not  
break my heart :-).

When deciding which Condorcet method is best some people put more  
weight on resistance against strategic voting while some try to  
optimize the output with sincere votes. Different environments may  
have different needs with respect to strategic voting. In environments  
where strategies are not expected to be a problem (in Condorcet  
methods) one may use the latter type of criteria.

Just wanted to point this out since you seemed to make the assumption  
that the best winner must come from the Smith set.
