I would like to nominate  Double Defeat, Hare.

*Voters strictly rank from the top however many candidates they wish and
also may specify an approval cutoff.

Default approval is only goes to top-ranked candidates.

All candidates that are pairwise beaten by a more approved candidate are
disqualified.

If that leaves more than one qualified (i.e. not disqualified)
candidate, commence eliminations according to Hare
rules until only one qualified candidate remains.*

This is a compromise between Hare and Condorcet which will probably not
please the fundamentalist supporters of either,
because it doesn't meet the Condorcet criterion and is more complicated
than Hare and fails Later-no-Harm and Later-no-Help.

But it addresses the concern some have about electing a weak low social
utility Condorcet winner, and I think it might simulate
well.

I've been meaning to suggest it here for quite a long time before this poll.
