Krita is not very good for photo manipulation. Even basic stuff like rectangle select and selection manipulation is painful. But on a project I used Krita, Gimp, and Inkscape all at the same time, and it was fine. Different tools for different purposes. Though with Gimp 3 having better font/text behavior, and overall allowing to build a pipeline of effects instead of immediately applying them (aka non-destructive editing), I could probably drop Inkscape now.
