I’m late to the party but windows Vista forced me off of windows. Not 5 minutes into setting up a new laptop and it told me even after clicking yes for admin privileges that I didn’t have the right to uninstall mcafee… I threw Debian on the laptop and never looked back. Ended up running FreeBSD for years on that thing and have mostly stuck with them since.

For Linux as others have stated lack of crashes and clear ways to customize/fix things was incredible.

FreeBSD doesn’t support all the newer standards yet (looking at you wifi6), but it is beyond rock stable. A month plus of 24/7 uptime between reboots for years and it’s just as snappy as when I first installed it. And even better they push hard to keep things more or less the same. The things I learned setting up FreeBSD 8.0 are still the same for FreeBSD 13. The biggest changes have been upgraded hardware support and quality of life tools that interact with the systems I was already using.

As a note FreeBSD does not come with a graphical interface. They have imo the best manual (handbook) for setting it up and getting going, and have native zfs for software raid arrays.

My risky two cents here is FreeBSD is great for learning all the ins and outs of Unix-like systems but is missing some things linux users take for granted like docker for servers (they use jails you set up yourself) and no cuda libraries for ai. If you have the time and want to learn how these systems operate from the ground up I find it’s better than arch. Easier to install, no compiling everything like gentoo, and an incredibly clean manual that has always made sense and worked exactly as expected. For just getting a desktop and easing into things there’s also nothing wrong with say Linux mint or any of the other recommendations others have said either.

The glory of Unix-like systems is they’re yours, and once you get used to how they run they’ll be rock steady for years and run faster than windows on the same device.
