When comparing Fusion Character Animator vs DragonBones Pro, the Slant community recommends DragonBones Pro for most people. In the question“What are the best 2D animation tools for game development?” DragonBones Pro is ranked 4th while Fusion Character Animator is ranked 6th. The most important reason people chose DragonBones Pro is:
This is a very useful feature because you can make a walk animation that you can simply change the animation weight to see the character start running, because it will increase the scale of the movement of the bones in the animation. This will increase the hand and the leg swing as you increase the animation weight and the character, making it appear as though it is running.

Cons

Publisher/ Developer dropped support for the software and left it in the dark. Use Spine instead.

It's not "free" if you can't save, and tutorials cost money.
