I see both products as awesome Zone alarm has its strengths and weaknesses i wont post the weaknesses but the great strength of zone alarm is that it can see outgoing traffic such as trojan programs thats the beauty of Zonealarm .Blackice has a great mini IDS for monitoring the network it often gives false positives because of the peer to peer networks out there that ping everything and search for Morpheus and Kazaa programs out there .I personally dont see any reason to knock zonealarm it does the job, just remeber this elf's/Warning any software based firewall sitting on an insecure platform is succeptable to that platforms weaknesses.
