I cant say I enjoyed modeling just with Nurbs and learning Maya at the same time. It was a complete change of pace from the simple and efficient polygonal modeling I am used to when working in Blender.
The biggest challenges were probably not being able to easily combine multiple meshes and unable to find the equivalent of face/point extrusion and face creation.
Hitting ingrained hot-keys over and over again didn't help either.
