IPFW or PF is fine for starting too.
The choise of the "best" firewall is, these days, more often than not an
issue of which one matches the specific application and the taste of the
one who is going to set it up, i.e.
* DUMMYNET is a very nice bandwidth limiting & shaping tool, which may
some times lead to choosing IPFW.
* On the other hand, PF/ALTQ may be used to do similar things, so some
users will obviously prefer this set of tools for other reasons (for
instance, because the like the ruleset style better).
* IP Filter, is almost obsoleted by PF on FreeBSD, but it's still one
of the most portable firewalls out there (I use it on Solaris all
the time, for example).
There isn't a "best firewall for all cases". They all have their
respective strengths and/or weaknesses.

I say, try them all out and choose the one _YOU_ prefer, for the reasons
that are important in _YOUR_ setup.
