Condorcet is easy for voters to move to for it is a strong, but  
simple, step up from FPTP and:
1.  Ranking means ability indicate order of varying desires of liking  
candidates.
2.  But ranking is much less of a task than Score's rating where you  
have to calculate the difference in value of A vs B, and express this  
difference as a number.
3.  More detail below.

Not against PR here - PR is not suitable for electing a single-winner.

Back to promoting Condorcet:

It is easier to understand the basics the voter needs to know:
1.  Voting is the same as for IRV, except equal ranking is also  
permitted.
2.  A voter familiar with FPTP can express the same thoughts, with the  
same definitions and power, by approving of a single candidate and  
ranking only that candidate.  Often few will want to approve more than  
one for offices such as Clerk or Coroner (but makes sense for ballots  
to permit ranking for the rare incidents of more controversy in even  
such offices).
3.  To emphasize point 2, a voter satisfied with FPTP voting is not  
seriously handicapped by not instantly learning Condorcet details -  
what is already known is enough to pick and rank a single candidate.
4.  Condorcet counting, unlike IRV's, requires reading all that the  
voters vote in one pass at each reading station and then combining the  
readings at one location to determine results.
5.  Do not have FPTP's need for primaries.
6.  Do not have FPTP's need for runoffs - because voters can express  
themselves more completely, the leader is deserving of winning with  
less than the majority that is truly needed with FPTP.

That the x*x matrix used in counting tells much about candidate  
strength, among the weaker as well as the stronger, can be useful to  
all who are interested in this data.

While there are a zillion Condorcet methods, picking among them is not  
that difficult if you select only among those that award winning to  
the CW when there is one (and there usually is - it takes three  
leading candidates to form a cycle and thus not have a CW).  Further,  
the situation we often complain about - having election power owned by  
two parties - says no cycle until some third party grows some muscle.
