Krita is a little unstable, but it's an awesome compliment to GIMP, and has an excellent set of brushes and FX which, IMO, are way higher quality than GIMP's. Plus, a beautiful dark interface...
Have been using Krita for about 4 months and created character illustrations with some basic brush. I admit the workflow is suitable for that purpose even using mouse as an input. Also the format interchange is working fine for most cases.
