Ranked in these QuestionsQuestion 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 Mesh Deformation
Instead of having to change sprites to bend legs or other joints mesh deformation changes the mesh shape based on joint weights to bend and move.
Pro Inverse Kinematic bones
Bones will move and rotate reacting to the position of the rest of the skeleton. The animator does not have to animate each part of a joint but rather have it follow realistically. Also can be used for ragdoll effects based on physics.
Pro Built on top of Unity’s animation system
Mecanim and state machines work natively since Puppet2D builds on top of Unity’s built in animation system.
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 Forced editor scaling causes problems
Puppet2D adjust the scaling of bones in the editor for display purposes, which results in unintended behavior if other objects use a bone as a parent.
