Hi Angela for the best workflow you possibly want to turn your vectors into AE shapes. You gain more control of the animation, and shape layers. One thing a person also has said to me is that a large complex heavy illustrator files converted into shapes will bog down after effects a lot. Also check out these resources: I’m sure your aware of the plugin from Battle Axe: Overlord, which aids you into bringing your vectors into after effects. Also on youtube search: The best Adobe Illustrator to After Effects workflow, for a very in depth analysis into this subject.
