This product is definitely greater than its constituant parts. While I didn't give any category a high rating -- "Sync E -> AB" does what the developer set out to do. Additionally, thanks to Paul B.'s excellent tech support (THAT should be it's own category!) I received what really was computer consulting advice as I had data integrity problems that didn't stem from this product. I do advise that you should carefully read the documentation -- don't just "do" this, or you could really muck things up. I do recommend using Paul B.'s "Import / Export X" to a) verify your Entourage's data integrity (especially high-ascii chars that cause problems with Address Book) and b) create a backup of your contact info.
