Well SolidWorks would not agree with you If you are coming from SolidWorks background and you just want more control over your surfaces 3DS suggests you use SolidThinking Evolve and it classifies it as class A surface modeler. Check it out yourself LINK
I'm pretty sure you can pull off a class A surface in Evolve with nurbs cause nurbs foundation is as same as it is in Alias. Once you venture into multisweeps and multiple rails then it's questionable how much of a control you have to pull of a ultra high quality surface. Maybe some of the sTE people can reply on that one.
It also depends from which spectrum you are coming from, if you are a product designer then go ahead and use Evolve cause it's ten times more natural and faster than Alias or any other established surface A tool. Advantage of Evolve or Rhino is that you can jump into the fire right away and walkaway with the finished product quite fast. Good luck doing that in certified class A surface tool such as NX or CATIA, I for once can't even choose the right version of CATIA cause there are so many modules, versions and what not. If you are a designer you also have the benefit of sending your model to engineers who already work in Alias or similar and they will rebuild the surface anyway if it needs rebuilding.
And then there is big BUT. Class A surfaces are all nice and dandy but outside of transport industry very few consumer products do include ultra high quality surfaces. Take your average Dell/HP/Lenovo laptops and look at those side edges, it's obvious with the naked eye that there are some distortions in transition. That could be a mistake in modeling or in production due to cost cutting.
