Ease of use(you can use the equation directly, instead of typing in a 
bunch of coefficients), more flexibility if it ever needs to be more 
than a plain paraboloid.

They might be faster...but maybe not. This is a pretty simple equation, 
and remember that isosurface superellipsoids often render faster than 
the superellipsoid primitive. The quadric primitive might be similar.
