One great feature of GIMP, entirely lacking in Photoshop, is GIMP's ability to ascertain the quality and chroma settings of a JPEG, and save at the same values. This helps reduce JPEG artifacting, which can get really terrible as Q levels change.

Furthermore GIMP is able to save 2x1 chroma subsampling, which is what most digital cameras produce. Photoshop cannot.

Neither of those are necessarily good things. JPEG are a poor choice for intermediate storage (which is the singke way to get strong accumulative compression losses) and 2x1 subsampling is far from optimal - in a camera that's acceptable because that usually is executed in hardware (more modern cameras will switch to video compression schemes because they are also executed in hardware and more efficient than JPEG).
