Use self.filtered_domain wherever possible for performance reasons and use self.filtered for cases where you can't leverage the Odoo domain syntax.

Use self.filtered when:

• You need to filter based on complex conditions that cannot be represented by a domain.
• You need to filter using Python logic, like checking computed fields or applying custom methods.

Use self.filtered_domain when:

• The filtering conditions can be expressed as a domain.
• You are working with large datasets and want to optimize performance by offloading filtering to the database.
