Hi alex, yes a lot of people find the mesh export to be much better and there are people who actually use MoI just for that function alone.

The then other main area is the UI but that's a quite substantial area that includes stuff like snapping and selecting things. For example when you move your mouse over an object in MoI to select it you'll see the one that you're currently over light up before you pick it. When you're drawing a line you'll see little tick marks where snap targets are that help you to home in on them. MoI's construction lines replace several specialized snap tools that are individual commands in Rhino, so once you get familiar with construction lines those kinds of things can go much faster. Since MoI incorporated the concept of sub-object selection from the beginning, it has allowed for a lot of condensing of commands, for example MoI's one fillet command can do a curve fillet, a polyline fillet, an edge fillet or a surface/surface fillet because you set the context including edges or faces being selected before you run the command. In Rhino those are 4 different commands.

There's really a lot of stuff to the UI, there's a big focus in MoI on making these basic things easier to do.

The overall focus of MoI and Rhino are very different, Rhino is fundamentally built on the idea of making something that's very friendly to users that have previous experience with AutoCAD, while MoI is focused on making things friendly to those without any previous CAD experience at all.

There are also plenty of people who like to use MoI and Rhino in combination with each other, doing the basic stuff like drawing in MoI to use the better snapping and selection behavior, and then go into Rhino when you need one of the many additional tools that Rhino provides.
