I'm also using gfi's mailessentials to handle the spam of my 100 users, and it does seem to be doing pretty well.
I have enabled the autowhitelist which has reduced the amount of false positives from my system. Only emails coming from 'unknown' senders are scanned by gfi after I did this. This also allows me to tighten the rules a bit more without having the boss running after because of a lost deal.
I have currently enabled sbl-xbl.spamhaus.org and bl.spamcop.net, both of which seem to be doing a very good job.
Finally, I have configured all the anti-spam features to move the spam emails to folders in the users' mailboxes. I think this was my best move, considering the amount of spam we receive.:)
