Which software product is best for data matching / deduplication?

For data matching we recommend Clean & Match, unless you just need to match on email addresses or other columns that require an identical match.  ListCleaner Pro does contain a module for data matching but will only find duplicates that are exactly the same (John Smith = John Smith, etc)  Clean & Match contains powerful fuzzy matching algorithms that will help to find names and addresses that are the same but are spelt differently.
