Components are smaller/modular parts; like a stat-component that is just a collection of variables that track health, stamina, etc.
Other components, like the movement, component do more functional things like help your character navigate, access the movement-queue, etc.
It depends on what you are going for. If it’s a thing that will be shared across multiple actors, then likely a component is the best way since it’s not something in and of itself, like an actor-proper, but something that enhances or adds-functionality to something it’s attached-to.
