Gizmo had some stuff on this recently
At this site they test all the major firewalls using leak-tests. Now outbound leak-testing is only one criterion for assessing firewall performance indeed some would argue that inbound protection is more important. My view is that both are important as are user friendliness, resource usage, software compatibility and resistance to termination by hostile agents. That said Comodo, Jetico and ZoneAlarm Pro top he list while the Microsoft XP SP2 firewall get the wooden spoon. ZoneAlarm free was another notable poor performer.

Interestingly, and perhaps not surprising, most of the suites dont do so well, with the exception of Kaspersky and Ghost Anyway gives you more to look at and to think about before parting with the hard earned $$$$s
