Recounting the transaction records to ensure that no records are missing is the best method to provide assurance that the best transactions were recovered successfully. This is because it ensures that all of the records that were present in the database before the snapshot was taken have been restored successfully. Other methods such as reviewing transaction recovery logs, rerunning the process on a backup machine, or comparing transaction values against external statements are not as reliable as recounting the records, as they do not guarantee that all of the records have been restored correctly.
