[EM] No. Condorcet and Hare do not share the same problem with computational complexity and process transparency.

As I mentioned in my reply to Rob, I agree that Approval wins the "bang 
for the buck" awards.

But talking about voting methods has to involve some amount of 
future-proofing. Otherwise there's a risk that the method will merely 
clear the current hurdle and then get stuck on the next one -- like how 
IRV clears the "fringe party" hurdle and then gets stuck when there are 
more than two serious candidates.

Suppose there are three serious candidates: A, B, and C. Your preference 
is A>B>C. Do you approve of A and B, or only A? Who knows. It's only one 
decision, sure, but it's not an easy one.

Condorcet's future-proofing would handle that case easily. What's the 
next hurdle? That would be sincere cycles or comprehensive coordinated 
strategy. For sincere cycles, something like RP is good; strategy? 
Condorcet-IRV hybrids or (hopefully) something better... which is part 
of the draw of tinkering with the resistant set.

If you want the simplest method that's better than FPTP, yes, go 
Approval. But beware the hidden cost that comes with offloading the 
dynamics on the electorate.
