Method evalutaion poll

Please rate the following single-winner methods on a scale from 0 to 10, on merit alone. That is, leaving the issue of public salability aside, how well will the method perform in a large, contentious electorate? Decimal ratings are allowed.

The answers you give on your first pass through the survey need not be final. Please feel free to change/update your answers as many times as you like.

Feel free to add new methods, especially interesting ones!
