Everything you could want from a skeletal animation system, free and because purchased by unity promises to be native in future.

Question Ranking
Pros
Pro Purchased by unity
Everything you could want from a skeletal animation system, free and because purchased by unity promises to be native in future.
Pro Free
Pro Spring bones
Much like spring joints native to unity, you can set bones to have dynamic spring animations based on their parents.
Pro Built into Unity 4.3+
2D game creation was a major feature request from the Unity community and was added with version 4.3. 2D is provided in both the Pro and Free distribution of Unity.
Pro Integrates with Mecanim
Mecanim brings state machines and blending to 2D bone animation. The state machine editor allows for designers and programmers to visually create a Finite State Machine (FSM) to control when animations should play. Mecanim also allows for blending so an animation can transition smoothly between two states without the need of in between frames made by an animator.
Pro Sprite Sheet and Bone based animation supported
Both types of 2D animation for game development are supported in Unity’s system and can be used interchangeably in the timeline.
Pro Easily change sprites dynamically
Usually used for character customization, programmers can change any sprite in a bone animation at runtime easily by referencing the bone and loading the new sprite from the resources folder.
Cons
Con No longer supported by Unity.
This has been merged into the 2D Animation package.
Con Uses the Unity hierarchy
It's impossible to rename your asset after making your animation, otherwise you lose dependencies.
Con Lacks critical features
- Vertices can't be animated, so you can't have ANY organic feel (like... lungs breathing).
- Parent bone can't be animated without affecting the children. This is especially impeding for organic feel, again.
- No option to show & unshow assets (or it is hidden), like for switching weapon on your character for exemple.
Con Poor script interface for texture atlases
Accessing individual sprites within an atlas texture is possible at runtime, but requires use of the Resources folder subsystem.
