I'm not sure.  The literature I've read so far says neither firewall
does traffic shaping AND supports active FTP in a deny-by-default
setting.  If google's to be believed, the generally accepted solution is
to use ipfw2 for DUMMYNET and ipf/ipfnat for firewalling and active FTP
proxying.

The combination served me well when I was using ppp(8) to drive a serial
modem.  Now that I've switched to ADSL and PPPoE, things seem subtly
broken.  I blame the user (myself), but I haven't found a solution after
beating on the problem for several days.
