FreeBSD supports 3 firewalls:  IPF, IPFW, and PF.  Some time ago  
(perhaps years) I seem to recall some discussion that one or more of  
those was better maintained and higher quality than the others.  I  
don't see any indications of this in the handbook.  Several years ago  
I needed to do traffic shaping and used IPFW with dummynet.  It worked  
but the need eventually went away.  More recently I needed to  
incorporate spamd which defaults to PF so I used that.  However, now I  
am back to needing traffic shaping again.  I suspect trying to use  
both PF and IPFW simultaneously will not be a good approach.  In  
addition, there now are instructions for using spamd with IPFW so it  
appears that either PF or IPFW will do what I need.  Is there any  
additional information available to assist in selecting between  
those?  Thanks.
