I think Ranked Pairs is the simplest "strong" Condorcet method. You sort
the pairwise victories so that the strongest comes first, then you go
down the list, adding that victory to the final order unless it would

So say you have

100 voters prefer A to B
80 voters prefer B to C
85 voters prefer C to A

which would give you:

First the result must place A higher than B. (Okay.)
Second, the result must place C higher than A. (Okay.)
Third, the result must place B higher than C... but that's impossible
because C is higher than A is higher than B. So skip it.

And the winner is thus C. A comes second, and B third.

On the other hand, Schulze is being used more widely, so it's a question
of what will be more persuasive: saying "this thing is simple", or "this
thing is used lots of places".
