Best Firewall

i was wondering what the best firewall for Windowsxp pro would be?
i hear sygate is prettyg good.

I use ZoneAlarm Pro and haven't had a problem with it, except for a weird glitch that seems to only happen with me and BF1942 when I'm playing LAN games....

I used Norton Internet Security (2001, 2002, 2003) for 2 years before I made the switch to ZoneAlarm Pro (today). It's much more secure, and the ports are now stealthed. Norton had the option of stealthing the ports, but they still showed closed on all of the port scanning websites. I've never used Sygate before.
