Hi basilhs, one thing that is nice is that as you become more accustomed to working in MoI you will probably find that things in Rhino start to make more sense as well.

There are also some nice tools in Rhino especially for deformation (like twisting and bending surfaces to follow along other surfaces), so sometimes it can be helpful to use MoI and Rhino in combination. It is pretty easy to go back and forth since both MoI and Rhino use the same file format and you can even use copy and paste to move objects back and forth.
