System-wide ISP systems are able better than personal spam detection systems. In the sense that an ISP gets thousands of emails, and when scads of identical spam hit their server, it can be flagged and deleted as spam. This is completely different from any system (ISP-supplied or not) that only assesses your inbox in isolation.
That's why I turned off local spam detection years ago, and have never looked back.
