the surfaces are much better, but are you faster.....yes?...no?...maybe?
MoI3d isn't really a Surface-Designer, but I show its possible to Design Surfaces, this is the base meaning of my Videos. You can create ready to render Surfaces with a "under 300 bucks Tool" but you must think.
Maybe Rhino have more Helfer-Tools for Surfaces (1000 dollar) it's also takes time:
maybe ProE, Catia, SiemensNX or Solidworks are much better but at look the prices.
In Moi3D is real CAD handwork without any big helpers, you must know what do, and why you do, but its much faster as Poly by Poly modeling in a Polygon based modeling tool like: Cinema4D, Maya, 3D Studio Max, Blender, Houdine, Modo
(the poly tools are 100% technical, to create a good meshloopflow und must have much more training.)
The Raw footage of my Hypercar Tutorial is under 8 hours, and I think it's fast enough for model a car exterior, without prebuild tests.
So I think if you need a "more time for design"-Tool you must spend much more money. And if a cheap surface designer gets to good, Autodesk buys it and kills it, or make the price super high: look for example: VSR Shape for Rhino.
