ImageMagick is generally more suited to processing photographic images; GD is
mostly for computer-generated "block" graphics. ImageMagick is also somewhat
faster for image processing (resize etc.) and can give subjectively better
results as there's many options for filters and convolutions.

The downside is that (a) it has to be installed in the first place and (b) you
may need to shell out to the "convert" command, although there are a couple of
PHP APIs that give you direct access to the ImageMagick API.
