Using COPY will always be *much* faster. PostgreSQL (latest versions at least) has an optimisation if you create a table in the same transaction as you load data into it. So, if you have a database dump, load it in using psql -1, which wraps the entire operation in a single transaction. Of course, a COPY dump will load a lot faster than a INSERT dump.
