Motion was a joy to use. I thought, due to its apparent ease of use, it might lack flexibility, and indeed, it did not have all the features that Adobe AfterEffects had. However, it was still quite flexible and I enjoyed using it quite a bit.
Autodesk Maya
Maya is a state-of-the-art 3D modeling and animation software package. I have used it in the past, mainly as a hobby, though I have a few items rendered in Maya on this website.
