Tough choice between OA free and Comodo v3. I vote for the latter as I have a couple issues with OA. Both are good firewall however and I would recommend either.
None. You can't answer because the poll is too limited. Have you stopped beating your wife? Yes or no.
Comodo Firewall version 3 rocks. I expect it to the top the next leak test beating online armor & outpost pro & the rest.!1
Comodo 3 over Online Armor as I also experience several problems with it on my setup. Comodo wins in the reliability stakes for me.
IMO Webroot is the class of this field. Great firewall (Private firewall clone) + a very effective HIPS with MUCH less user harassment (& NO bugs) than is true for Com3.
The poll is too narrow, because I try to focus on specific firewalls. There is a reason behind this: Although Agnitum Outpost firewall Pro 6.0, tested 100% at matousec.com, many users complained about it and its spyware detection (see the relevant Thread). Therefore, I tried to inlude ONLY firewalls that a) scored high at matousec.com (i.e. Online Armorv2 & Comodo v2) and b) are expected to score high in the future (i.e. Comodo 3 & Webroot 5.5) Once again, thank you for participating!!!
I think OnLine Armor is good, but I uninstalled it (their past version) coz it almost takes forever before I can see my desktop when I log-in and I could not return to see again what I have allowed and blocked on its first run of installation.
I know that this one is criticized by a lot of folks, but I use Windows Firewall because it's easy to use and personally, I dislike the "learning" process that some firewalls require and Windows Firewall basically runs by itself.
Usually the one built into the suite I happen to be using or Windows Firewall. Voted Comodo 2 since it's the most I've used with stand alone firewalls and liked it the best.
I tried all of those listed and would vote for Comodo 3. But at the same time I have to say that ZoneAlarm Pro is my favorite of all FWs because it is very effective and imho has the very best interface of all of them (by far).
