For me, it still mostly comes down to usability. A big part of it is probably that I just have more experience with Photoshop, and if I really forced myself to use The GIMP more, it might grow on me... But when I am working in Photoshop I always feel incredibly productive, where as whenever I have to use The GIMP, I feel like the interface is constantly fighting against me, trying to keep me from getting my work done.
