Hi Arthur –
I teach in the motion graphic design department at Expression College for Digital Art. Our department used to teach Maya, but as Randy said, found Cinema to be a faster learning curve. We also find that the jobs our graduates get in the motion graphics field require that they now know Cinema 4D. One of our other departments, the animation and visual effects group, teaches Maya since these are the people that will be going out and working on large movie productions (creatures, large visual effects, etc.)and Maya is the industry standard there.
I have personally used several 3D packages in my career, including Lightwave, Maya, Soft Image and now Cinema 4D..and I love Cinema now. I’m not sure if I’ll ever go back. Oh, and Cinema 4D has a nice workflow with After Effects.
Just my two cents. Hope these answers help you make a decision.
Tim
