Do they really compete with each other? I thought they would complement each other, am I wrong?

I use Krita for painting and sketch work (animation now) with my Wacom or Surface Pro, I use Gimp or FireAlpaca (new on the scene) for manipulation and finally Promotion or Aseprite for pixel work. There is really no killer drawing application that does it all. Which is probably a good thing.
