Best resizing method for high-quality downsizing

Which method is the best for downsizing an image while preserving the most possible quality and sharpness?
Speed, Memory, Perfomance and such things aren't important for me - I only want the maximum possible quality.

Thank you for your help!
With best regards
Innocentus

Have you read http://www.imagemagick.org/Usage/resize/? If you do not want to use expert settings, the default -resize option does a superior job downsizing with a Lanczos filter.

So the Mitchell-Filter is better in high quality downsizing than the Lanczos-filter?

We default to Lanczos for downsizing and Mitchell for upsizing (see the edit in our previous message).
