Unless your running quite a complicated setup or have specific requirements then there isn't really any preference for one over the other. If you're running a typical home system, even with say, a 10Mbit/s cable modem connection, any reasonably modern FreeBSD machine is going to be able to do firewall filtering without breaking into a sweat. You'ld need so quite fancy hardware to detect performance differences between the two. Probably the biggest reason to choose one over the other is simple personal preference between the different rule-set styles. ipfw is 'first match wins' (hence rule sets tend to be ordered from most to least specific). ipfilter is 'last match wins', so the most general rules tend to go at the top of rulesets -- although there are special 'quick' rules that can shortcut the process. In general both firewalls have very similar functionality. ipfw(8) can act as a filtering bridge and it can provide weighted fair queuing and bandwidth limited pipes in conjunction with dummynet(4). ipfilter seems to have more complete IPv6 support than ip6fw.
