I love GIMP! Never used adobe stuff, so I don't really have anything to compare it to; but I cannot imagine in what sense Photoshop can be much better than that. Still, there are some improvements that I yearn for GIMP that are not likely to ever be considered. Everybody seems so intent to make a tool for dealing with photos and synthetic color images, to the detriment of other kinds of images. For example, in scientific imaging, you would need to deal with floating-point valued pixels, and an arbitrary number of channels (more than 3 or 4). If you work with images coming from microscopy or satellite images, then every pixel typically has a lot of spectral bands that cannot often be reduced naturally to RGB, but you'd still want to map them in an arbitrary way and edit them in GIMP. This is far from being possible today.
