Not to mention that PFSensenormalizes a lot of management. It provides an easy mechanism to queue changes and apply them, lof when changes were made and what the changes were, etc.
In a previous job we used to deploy OpenBSD firewalls to provide site-to-site VPNs. We switched to PFSense because management was easier when you have 10-20 of them to deal with, and multiple people might have access.
That said, we definitely would have preferred an equivalent interface on top of OpenBSD instead of FreeBSD. There were some differences in the CARP implementation in FreeBSD that made some features of CARP we relied on with OpenBSD unavailable in FreeBSD, and thus PFSense.
