Instead of dropping the DBs, simply restore to another database or server. That will also
allow you to perform a comparison using some graphical tool, or if that fails mysqldumps

Filesystem level won't work, as it's fairly unlikely that the records will have been
written in the same order - let alone that you won't have delete gaps etc.
Percona toolkit has tools to verify master/slave setups (pt-table-compare, I believe), I
suppose they would also work on non-replicated setups.
