The GDPR was a regulation - a type of EU law which immediately applies uniformly in every member state.
This proposal is different because it is a Copyright "Directive" - directives leave the implementation details up to the member states. If a court rules a particular member state's implementation to be in violation of the directive, the directive's wording has the supremacy and overrides the local law. Still, this leaves some leeway for member states. They may choose different approaches to reach a common EU goal, or more lax/stricter punishments provided that the directive allows for that.
