I found the same about moving to GIMP from Photoshop. Granted, Photoshop has more conveniences and fancy features. But a good deal of the frustration is not GIMP's so-called confusing interface, just the habits I formed while using Photoshop. Now that I'm a GIMP user for a time, every time I go back to Photoshop, I find myself annoyed in the same way. I think this just boils down to people's natural resistance to change.
