Raspberry Pi OS works, is supported. Why select and use GhostBSD-Arm64?

Raspberry Pi OS works, is supported.  Why select and use GhostBSD-Arm64?   Why would you choose to port FreeBSD (GhostBSD-Arm64) to the Raspberry Pi 4B?  Well I had experience installing & running PCBSD on a x86 laptop in June 2014.  Then I  went back to work and the next time I had time to install PCBSD was October, November 2016, yet there was no PCBSD available then.  Looking around I found https://GhostBSD.org/download and installed GhostBSD.  Networkmgr python app was not working for me.  So I studied about setting up wifi manual using google searches.  I will share forum posts related to that wifi learning experience. https://forums.ghostbsd.org/ucp.php?i=pm&mode=view&f=-1&p=162   Letter Note I wrote about my noob experience with GhostBSD in December 2016. https://www.zenarmor.com/docs/linux-tutorials/freebsd-vs- linux#:~:text=Linux%20is%20compatible%20with%20a,resources%20available%20to%20support%20it. Here is a great description of freebsd versus linux.
