      The default NTP source for pfS is 0.pfsense.pool.ntp.org.

      In the past I have always used us.pool.ntp.org.

      Is there any reason not to keep using the default?

        Always select the geographically closest pool, for you the proper ones would be:

        http://www.pool.ntp.org/zone/us

        Give the ntp service all four of the addresses for added redundancy.

          IIRC the pfSense team was asked to use *.pfsense.pool.ntp.org as default by ntp.org just in case there was anything going wrong with queries from pfSense they could easily revoke name resolution. cmb posted about this many, many moons ago.
          Using a server close to your location is always the best choice.

            As jahonix mentions, any software that wants to put in a url to pool in their software as default is asked to create their own unique fqdn for the pool, etc. So this is pfsense playing nice with ntp.org

            http://www.pool.ntp.org/vendors.html

            Anyone smart to even look into where or what its using for ntp should prob change this to either their own ntp servers of choice or the fqdn pool urls for their region of the globe.

            For example if you want to use the pool and your in the US you should use say

               server 0.us.pool.ntp.org
               server 1.us.pool.ntp.org
               server 2.us.pool.ntp.org
               server 3.us.pool.ntp.org
            

            You can find a full listing here

            http://www.pool.ntp.org/zone/@
