I found the textures interesting but the interface needs work.

There is not output for CMYK or Spot Color. So it is lacking things.

Xara has customer support even though the Spot Color and CMYK isn't there either but Xara is fun, fun, fun.

And the tools work predicatably so if you want to make something or go back to an old drawing and pick up from where you left off, you know what you were doing.

One I have tried lately that I really like is Deep Paint. It is a great stand alone program. It isn't about the sorts of drawings Xara does, it is more about texture. As a plugin it is fantastic.
