Whilst BSD isn’t linux per se, it still has a lasting legacy in the unix like space and notably has been used in game consoles like the PS4.
For you in your personal use case, have you tried a bsd distro? What was better compared to the average linux distro?
Apparently BSD is more modular with its jailing system and seems to have a lower resource usage.
I look at ones like NETBSD and FreeBSD and think, "what exactly do I get out of them that I wouldn’t with Linux say, Ubuntu or Void as an example?
What are your thoughts on BSD, you use FreeBSD before?
Your point is well taken and I appreciate expanding my knowledge on this a bit, but I don’t think that it is that cut and dry. Mach, the kernel from which both is not Unix. Mach is basis for XNU (X is not Unix, sound familiar). From the screenshots from Wikipedia, pretending that BSD is not embedded within MacOS is just trying to obfuscate things. The Mach virtual memory manager for instance is in FreeBSD, so it goes the other way around as well.
