attachment vs Docking

Is the basic difference between attachments and docking is that attachments doesn't affect the mother vehicle's mass.

I am working on a Spacedock. Wondering if I should make docks or attachments for docking/attaching with the station.

I like Docking as you can get a signal to align with the dock. But not sure if you can add docks to a existing vessel as you can with attachment manager.

Attachment points can also be changed in their position and orientation while something is attached, while docking ports don't allow that.
