You are getting dangerously close to the often stated claim that  
Range would turn to Approval in the presence of insincere voter  
groups. :-)

Probably a typical person studying Condorcet does not see it as a  
better utility function than Range. I believe it is typical that  
Condorcet sympathies are based on its ability to reach pretty good  
utility and strategy resistance at the same time.

Maybe many also think that due to the varying sincere preference  
strengths it is better to give each voter one vote (all of same  
strength) (=one man one vote principle) (A>B>C means A>B, A>C and  
B>C, all with strength 1). This can be considered ideal by some  
although this does not aim at maximising utility but at minimising  
the number of voters that are unhappy (=never mind how unhappy they  
are) with the selection. (Condorcet typically compares only one  
pairwise decision at a time, which may be considered a weakness, but  
I leave that discussion to another time.)
