Basically there are 4 main branches of BSD. - FreeBSD: The most popular, and the most optimized in terms of performance. - NetBSD: The one that supports the most platforms - OpenBSD: The most secure, so much so that it is the operating system with the least vulnerabilities in the world. - DragonFlyBSD: The most innovative, it has a file system called hammer, virtualized kernels... For a normal user I recommend FreeBSD.
These might be good recommendations for FreeBSD on the desktop, especially GhostBSD. https://ghostbsd.org/ https://www.nomadbsd.org/
Weird, my client only shows a preview for NomadBSD. Trying again... https://ghostbsd.org/
