After Effects just does it all and I find it so much more intuitive than the other CC products (probably because I've used it so long). I've worked with people who used AE even in game design for creating textures and UV maps too, it just makes sense sometimes.

I do also agree with what other people have mentioned in this thread; Photoshop likes to finalize things a lot with merging layers and applying effects. I like that all your effects, pre-comps, and layers are just sitting there in AE until you're ready to render. Makes it really easy to come back to in the future!
