Windows XP SP2 fireall is the last resort - it has one serious flaw - if

which also greatly exposes you.
No other firewall is different. If you are administrator you can change the settings of any firewall running on your system. No firewall running on the computer can prevent that. Thus, if a program wants to open a port it can do so if it is running as administrator. Maybe the installer of the program does not care about opening the port on a 3rd party firewall but still it could do so. It is usually not necessary anyway because people running personal firewalls tend to turn off the whole firewall whenever there is a networking issue, anyway.
Moreover, the firewall does not "default" to allow file sharing. The default is to block sharing. However, if you want to share files and run the file sharing wizard the necessary ports are opened. This is very reasonable as it helps people to achieve what they want to achieve: share files in their network. With other personal firewalls people have a much harder time to figure out how to get it working. Many file sharing problems are due to 3rd party firewalls.
