hosted anti-spam services, Postini vs. Messagelabs

Does anyone have any experience with hosted anti-spam services?
Which performs better/has more features, messagelabs or postini?

We use postini and love it. It is very simple to setup and does a great job
of filtering. We have been customers for 5 years.....way before google
bought them. don't have any info on messagelabs. Post back if you need more
info.
