I use Fusion 360 mostly for jewelry design. The biggest missing creative capability with Fusion 360 for me is global defomations: The ability to take an arbitrary model (or volume of space) and deform it, for example using an FFD cage, or other deformer models (twist and bend probably the most important alternatives).
I use another software package that allows me to do this with arbitrary models (solids and surface models), and it is incredibly useful: Many shapes I create are much easier to model un-deformed, and then deformed as a whole. Key to this is globabl deformation of an entire model hierarchy, not just of individual parts.
