HI MIchael,
"Organic models tend to work better with sub-d modeling, where things work kind of more like sculpting where you're working on manipulating a cage of points in 3D space."
Just want to add some words.
Here we say that there is Nurbs for hard surface and SubD for Organic. I think it is right only in context of MoI. Because there is Surface Modeling and it is also Nurbs and allow to create very complex organic shapes. But MoI have no Tangent option in tools like Loft, sweep, network, also it lucks some tools. You can get out from some situations using Blend but you can not go far away only with this tool.

I just want to clarify for some new users, that for creating Organic shapes there are 2 ways:
SubD and Surface Modeling.
With Surface modeling you have deal with Surfaces not Solids. MoI now is greate for Solid Modeling but Surface Modeling in MoI is not so good.

For SubD you can use Polygonal Modeler (Quality of surface is not very good) or any SubD module that now has a lot of CAD software(it has much better quality than polys).
It is very fast and simple method. But it is so hard to control precision, fillets and other...

Or you can use Surface Modeling, quality of surface is superb, and you can control everything with precision. (SolidWorks, Rhino, Alias, Fusion 360, SolidWorks)
For some people SubD is more simple for another Surface Modelling is more intuitive.
