I’ve found that Motion is the perfect compliment to AE. It can create some great textures and also inspire you. However, I usually create some texture or background, then bring it right back into AE. Motion IS much faster and that is a threat to AE. I have seen a demo where they hooked up a camera and greenscreen, ran it live through Motion with a key filter. They were able to adjust the lighting, etc and set up a perfect key. I LOVE After Effects and will never leave it, but Adobe needs to be careful b/c some people (including your bosses) will start going to Motion for the speed, not knowing or caring about the “art” of After Effects.
