I hope you don't mean Adobe's Photoshop and Illustrator. I tried those a couple of weeks back. Compared to Gimp and Inkscape they are as buggy as hell. Simple .png export with custom dpi often doesn't export to custom dpi. Exported images often aren't pixel-precise if you repeat the export and layer boundaries somehow suffer from float rounding errors if you load/save the file multiple times. I find it amazing how supposedly professional tools can have such major problems. I guess it's just good marketing.
The only thing missing in Gimp is CMYK support and that might be sole reason people are still using Adobe products.
