The comparison does not work, because I think Krita is a better general purpose editor than GIMP. You can keep declaring Krita being a hammer, but you are wrong. Krita is not a single tool, it is a set of tools that includes a hammer and a drill. While GIMP lacks the hammer and only has a drill. These metaphoric comparisons are just misleading.

The UI is not the problem in Krita (can be personalized anyway), it has more features for general purpose editing than GIMP. You just keep telling people that Krita was not designed for the task. It does not matter. Because it has the functionality and is well build for general purpose editing. You are just victim of the marketing.
