FreeBSD has 3 different firewalls, not 3 different interfaces to the same firewall. Each firewall has its own purpose. IPF is lightweight, pf has a nice UI/UX, ipfw is very integrated into the system.

More importantly, doing a simple kldstat would tell you which firewall is running. On Ubuntu (as an example) I have no idea if I should be using nftables, iptables or if ufw is working or not.
