Heh. Whenever you ask someone who doesn't work with image editors professionally (that doesn't mean "use it quite often", it means, having real-world deadlines depend on productivity), they'll point out how many "features" Gimp shares with Photoshop. But features don't mean shit. The interface is a bulky mess. Tons of "little" things don't quite work as expected. And then, when it comes to the truly heavy-weight features, of course Gimp doesn't compare.
Out of curiosity, I tried installing Gimp to see how much has changed (for the better?) since I last checked it out. The tool interface doesn't quite fit into its window by default so you have a tiny little scrollbar at the bottom that you have to scroll to see the full text. I resized it. After popping out a submenu, it once again didn't fit.
Free/open software projects are so idealistic, I kinda want to support it. But it's so rare that anybody in these communities gets interface design. It's not unheard of (Firefox is a positive example in my book) but it's rare. Photoshop's main advantage is it's clean interface: http://f64academy.com/wp-content/uploads/2013/06/The-Interfa...
