Ranked in these QuestionsQuestion Ranking
Pro Free and open source
Blender is licensed under the GPL.
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 Wide import and export format support
Support lots of modern 3D formats including DAE and FBX - ideal for game developers.
Pro Includes a complete game engine
Blender has a complete game engine. It features node based scripting (called Node Editor), Python scripting, dynamic shadows, bullet physics, animated textures and more. Combine it with the ability to model, render bake and texture paint inside the same application and modify the source code because of it being free and open source, Blender becomes an excellent choice for making prototypes and even complete games in considerably low amount of time.
Pro Regular release schedule
Releases are made every ~3 months.
Pro Supports both low-poly and hi-poly modeling
Pro Includes video editing & compositing tools
Blender's node-based compositor has comprehensive video sequencing and post-processing features.
Pro Has a good 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.
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 It has sculpting and 3D painting features
Although blenders 3d painting and sculpting tools (mostly painting) are not at par with specialized software like Substance painter, z brush, or mari; it is more than capable of getting most jobs done if the user takes the time to learn and understand it.
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 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 Allows users to create and edit RAW profiles
Unlike most other RAW editors, LightZone supports user-created RAW profiles and allows editing existing RAW profiles.
Pro Allows changing the order in which adjustments are applied
You can change in what order sharpening, saturation, tone, etc adjustments are applied simply by switching around their order in the tool stack.
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.
Con Asset management is basic
Browser module includes a file browser, metadata viewer and a really basic metadata editor (allows editing just 6 fields), and allows you to give images a rating, but no advanced asset management is supported. There's not even a way to assign keywords to files.
