Chromatic Aberration is a normal artifact that occurs in all cameras. Sometimes it's a desired effect with making digital images. After Effects has many plugins available to it to achieve this effect but After Effects is perfectly capable of creating the effect on it's own.
Light wrapping objects in compositing is a common task. There are many ways to achieve this effect in After Effects, some are with plugins. Sometimes those plugins aren't available to use. With a bit of precoming it is possible to achieve the light wrap effect in After Effects without any plugins, which makes it easy for other users to open project files without the worry of having the necessary plugins.
It is important to work as fast as possible when working in the viewport. Often times models will slow down your viewport. Making a proxy with a bounding box around the higher resolution model will free up memory usage in the viewport.
Making mask wipe animations in After Effects is a pretty easy thing to do. Mask Whips in Cinema 4D is bit more complicated due to the nature of 3D. Using a bit of Xpresso and using gradients to drive the alpha channel can achieve mask wipes easily to achieve in Cinema 4D.
Mograph's Inheritnace Effector offers the ability to be able to reference a keyframe animation and transfer it to clones which enables you to quickly duplicate the animation and offset it to other objects.
