Do you even use gimp?  When downsampling gimp will use bilinear
filtering even when bicubic is specified.  There are usefull techniques
that require the use of nearest neighbor or bilinear resampling.

I'm not sure why gimp would do a better job of downsampling than
imagemagick.  It doesnt do anything fancy, just a rectangular
