In tag matching mode dupeGuru 4.1.0 displays more tags than Duplicate Cleaner (or any other audio comparison tool I have tried). However, Duplicate Cleaner (Pro 4.1.4) also displays embedded artwork, which dupeGuru does not. Duplicate Cleaner compares both tags and content in one pass, whereas content matching is separate from tag matching in dupeGuru. Furthermore, the content matching criteria can be adjusted in Duplicate Cleaner; in dupeGuru they are neither clear nor adjustable.
