Just keeping it simple here, as earlier said by many & reputed, Comodo hardly has any competition. Just check this out Firewall Test Results. You'll also find Outpost Security Suite Free doing great too at 4th place. Also, look for PC Tools Firewall, though they have tested it as entire security suite instead just FREE firewall. Good Luck.
