Is there an image editor like Windows' Paint for OS X?

I tried out several image editors mentioned on this site but some of them (like Pixen and Seashore ) were very disappointing. These apps were too simple and low level. What do you suggest for a **(preferably free)** image editor on OS X? P.S: I was using GIMP on Linux and also know that it was released for OS X too, but I want to find new good applications.
