Wall fan, is better Skin animation or blueprint?

I have a lot of wall fans in my levels.

I wonder if is better use a skin animation to move the blades or export separate the blades and make a blueprint.

Any advice about?

you can even use world position offset in material, to make them turn. use Rotate about axis function.

but it is not physical rotation, only visual.

if you need physical - better use blueprints.
