CREATE OR REPLACE TABLE, because it allows for the complete replacement of the target table with the current state of the source table, ensuring data consistency but at a higher operational cost due to the recreation of the table.

INSERT OVERWRITE, because it efficiently overwrites the target table with new data from the source, but fails to account for deletions, leading to potential data inconsistency.

COPY INTO, because it is designed for efficiently loading data into a table and can prevent duplication, but lacks the capability to handle deletions, making it unsuitable for this scenario.
