ffmpeg GIF output ugly.

Am I missing out on some important command line syntax for quality, or is ffmpeg's GIF encoder really lousy?

Original JPEG :

Transcoded into GIF with ImageMagick convert.exe :

Yes, I know GIF isn't targeted on photos. However, with it's 256 color limit, it still seems able to encode "descent" output through ImageMagick (I also tried another converter, with similar results). Also, when running a color counter on the output, it seems that the ffmpeg-produced GIF only uses 103 colors, whereas encoded by other software go up to the 256 limit. Strange? What am I missing out on? Is ffmpeg GIF buggy or what?

This is my command line:
ffmpeg -i original.jpg -pix_fmt rgb24 output.gif
