To my way of thinking, the OS itself matters only if you're developing or supporting the OS, or doing development for that OS. Otherwise, the overwhelming criteria are what applications are available. I use Adobe Lightroom and Photoshop for my photography, and those are available only for MacOS and Windows. Because of very bad experiences with Apple as a developer of apps for the iPhone, I don't like anything Apple, so I use Windows for my desktop and laptop, and an Android phone.
I often hear that there are Open Source equivalents for Lightroom and Photoshop, but the people saying that aren't serious photographers.
If you don't require any particular applications, then, as I said, the OS doesn't matter, so Linux and FreeBSD are fine choices. I've long been impressed with how usable distros like Ubuntu have become over the years.
On rare occasions, I need to run a UNIX/Linux program, and for that I used to use the MacOS command line back when I used a Mac, and now use Windows System for Linux, which runs Ubuntu.
(Like everything else posted here, these are my opinions, likely not anyone else's.)
