vacuum vs pg_repack for clearing bloat?

Our app makes extensive use of temp tables, and this causes a
significant amount of bloat that can often only be cleared with a manual
vacuum process. We're looking for a better way that doesn't involve
locking, we found pg_repack and pg_reorg  and were wondering if anybody
here could weigh in on using this instead of using vacuum?

pg_repack:

Thanks in advance,
