Also, Borda and Woodall's descending coalition methods have been at least 
discussed here.

IRV meets Mono-add-top, meaning that adding new ballots with A as the
first preference can't make A lose.  It seems a method meeting Schwartz
and Mono-add-top hasn't been discovered yet.

Later-no-harm is technically an advantage over Approval, one that gets
brought up quite a bit.
