When comparing Adobe After Effects CC vs Blender, the Slant community recommends Blender for most people. In the question“What are the best and easiest tools for editing and creating video animations for Windows?” Blender is ranked 2nd while Adobe After Effects CC is ranked 4th. The most important reason people chose Blender is:
Blender is licensed under the GPL. Some Blender modules such as the Cycles rendering engine are licensed under the Apache 2.0 license.

Ranked in these QuestionsQuestion Ranking
Pros
Pro Great for motion graphics compositing
Ae is the de facto standard for motion graphic design.
Pro Huge amount of resources
Because of the popularity of Ae, there are a plethora of tutorials, presets, plug-ins, etc that can be used.
Pro Extensive plug-in support
After Effects has extensive plug-in support. A broad range of third party plug-ins are available including solutions for particle systems, 3D environments and grading.
Pro C4D Lite & Cineware integration
After Effects CC includes a Lite version of MAXON CINEMA 4D, a 3D modeling, animation and rendering application.
Pro 3D camera tracker
Pro Speedy and comfortable UI
After grasping what panels do what, the workspace feels safe and comfortable. And the timeline moves and shows things how you would expect it to.
Pro Works well with other Adobe software
This program is made to interact very well with the other Adobe production apps like Premiere Pro, Soundbooth, Photoshop and others. You can dynamically link with a set list of Adobe software so when you update something in Ae it will update in other software accordingly.
Pro Subscription / cloud-based model
Ensures you always have the latest version of the software. Allows saving preferences in the cloud, so you can load them on a different machine. You can even sync setting from a different user.
Pro Subscription based model
You constantly have the latest software that is updated regularly.
Pro Ray-traced and extruded text and shapes


Pro Free and open source
Blender is licensed under the GPL. Some Blender modules such as the Cycles rendering engine are licensed under the Apache 2.0 license.

Pro Wide import and export format support
Support lots of modern 3D formats including DAE and FBX - ideal for game developers.
Pro Has a powerful rendering engine
Blender runs the Cycles path tracing engine under the hood. Cycles is a very powerful rendering engine capable of full path tracing (light fall off, caustics, volumetrics). It is mostly compatible with OpenCL and CUDA rendering, and is implementing mycropolygon displacement features. The upcoming release has a viewport engine called EEVEE whereby you can see and interact with your work in render mode in real time!

Pro Python extensibility
Blender embeds Python 3, which can be used to write add-ons, tools, extend the interface, rig characters and automate tasks.

Pro Powerful animation suite
Blender provides a full rigging system, and automates animation by interpolating between keyframe positions.
Pro Supports both low-poly and hi-poly modeling

Pro Regular release schedule
Releases are made every ~3 months.
Pro Sculpting and 3D painting features
Although Blender's 3d painting and sculpting tools (mostly painting) are not at par with specialized software like Substance Painter, ZBrush, or Mari, it is more than capable of getting most jobs done if the user takes the time to learn and understand it.

Pro Includes video editing & compositing tools
Blender's node-based compositor has comprehensive video sequencing and post-processing features.
Pro Node based modeling support
Pro Keyboard shortcuts
Good keyboard shortcuts for everything. Keep your left hand on the keyboard and your right hand on the mouse.
Pro Very useful for a freelancer
It offers a round solution (it covers many areas and professional fields) for a freelancer, for free, constantly updated, very polished, and allowing high quality results that clients do require. After some learning, it becomes very useful for professional work.
Pro Has a large community
There's a huge community to help you get started immediately.
Pro Coherent and streamlined workflow / internal use logic
The trick with Blender is to get used to its usage philosophy, as it keeps consistent through all the application. Once you get it, every feature or addition is learnt naturally, almost effortlessly.
Pro Very versatile
You don't have to switch between software when you want to do different things. Because modeling, sculpting, composting, video editing etc can all be done in blender.
Pro Generative geometry using nodes
Cons
Con No true 3D environment for compositing
Con No real-time features
Con Costly
The Adobe subscription costs are quite steep for anybody on a shoestring budget.
Con No stereoscopic editing support
Con Too many possibilities, no unified workflow
The operations are not optimized enough for specific tasks.
Con The physics engine is a bit lagging behind, especially the destruction physics
Con Difficult learning curve
Blender has a history of being unintuitive, but the 2.8 overhaul made the program far easier for beginners to pick up, and changes continue to be made to further improve the experience. However, there is still a learning curve.
Con Not good for Industrial Design because it uses average vertex normals
You can not create a hard surface with a radius continuity degree along a surface using a specific radius value.
Con Vertex normal issues on edges after boolean operations.
After creating a simple boolean operation the vertex normals are broken. A lot of work to fix the issue and you loos surface continuity.
Con Bad vertex normal after boolean operations
Does not handle well polygon intersections. And need tweaking by hand points or adding average vertex normals via modifiers.
Con Does not handle NURBs
Is not capable of real hard surface for industrial design because is not able to reproduce surface continuity degree as a NURBs does and average vertex normal destroy surface radius.
Con Poor particle system
The Blender particle system can at times be a little limiting and finicky (and buggy) to get working. Even if it can get most straight forward jobs done, it is far from the most advanced system, and could benefit largely from advancements.
