Yes, if you're interested in creating a NURBS object from a mesh then no, it wouldn't help.

Thing is, unless you're expecting to export out to a NURBS format, you're going to get polygons back out anyway.

The tools I mentioned are typically used to clean up .3DS and other dirty polygon meshes into a nice quad structure ready for animation etc.

Their inexpensive prices make them handy tools to have just for GP...
