UV mapper is pretty crude but you can do some simple shapes prettty quick but I would not use it to map say a human figure no unfolding options. Texture coordinatior you can use liek Wings make colors and then in your renderer you can apply different mats to your colors.  Soem cool tools in it. Like the mirror tool not as good as wings for organic things but say you are makign a car you can mirror the tires and they will show up at the right spot on the other side of the car. Try the demo see if you like it. No displacment painting though.
