I think it's ok for switching to be hard if the UI is built for productivity. I'm not really a "creative" worker in the most common sense, so I'm guessing GIMP's UI sucks even after you learn it, but I do know VIM is not intuitive at all, yet improves productivity compared to most IDEs/text editors. I've also worked on an application, working closely with our somewhat technical users, and they would suggest UI changes that were often not intuitive, but increase their productivity a bit (less need for using a mouse, less keystrokes/clicks and stuff like that).

YMMV but I've found the GIMP UI to be pretty much on a par with photoshop after having learnt the UI and learnt/modified the keyboard shortcuts. Some things are in fact better in GIMP, like panning and zooming. I've transitioned to GIMP on my own hardware but still use photoshop at a workplace.

If photoshop was open source then I think there would be a conversation to be had but I wouldn't pay for it now that I'm used to GIMP.
