There's something about the way you write that's hard for me to 
understand. For instance, I don't know what you mean by "demonstration" 
here.

But on the general point: I doubt the results will be different between 
Condorcet methods, except perhaps up to ties - some methods will return 
more ties than others. That's why I suggested a method that has a low 
tie rate.

We do know what we would find, though: the accumulated opinions of the 
people who participate, about what methods are more suitable than others 
for political use.

There are so many methods because yes, there is an impossibility. We 
can't have every desirable criterion at once, so we have to choose. Namely:

Arrow's says that there exists no ranked single-winner method (apart 
from certain random exceptions not listed here) that can't be made to 
change its mind by removing candidates who didn't win.

Gibbard says that you can't be strategy-proof: whatever your method, it 
will sometimes pay to vote tactically.

Duggan-Schwartz says that the impossibility of being strategy-proof 
remains *even for multi-winner*, unless you elect every candidate who is 
someone's first preference.

I would hardly dismiss them.

I wouldn't say single-member district is the best of all possible 
worlds. I might even say that better democracy reduces the use of 
elections, by using selection by lot combined with deliberation instead. 
But for the situations where you have to use single-winner, it's a good 
idea to know what to use. Or to have a selection of good methods to 
choose from.
