I've been using ZoneAlarm for a very long time plus a hardware router firewall, so I might not be able to give a qualified opinion on other software firewalls; however, I know that COMODO firewall is also highly valued ( anyone who have used this or any other firewall is welcome to add their opinion). Also the one of the very simple ones is the Windows' own firewall, though it's effectiveness have been questioned many times, but I haven't heard that it gives any conflicts or other glitches. (I might be under-informed on this, though.)
