If you want to morph, they are perfect for that.

If you want to sculpt? I have to say, too few poly's for detailed work.

You can use Hexagon, or Blender or Zbrush, first morph, and then build a displacement map in there for the detail work.

And default?
There are some mesh problems that need to be corected first, mostly in the head.
