The problem with NURBS is that you very quickly need trimmed NURBS to model anything of even modest complexity, and those are unpleasant for software to work with.
I've been toying with the idea (not new) of triangular NURBS which could do away with the need for trimming entirely. Questions remain about which type of triangular surface patch will meet the requirements.
