OpenBSD.

puffy, the mascot for OpenBSD.

I have OpenBSD running on a Raspberry Pi 3B+ as a home server hosting this wiki. I really enjoy the secure-by-default stance, quality documentation, and all the nice things they've added to the OS to help applications be more secure. It's quite well-suited for server applications.

I used to run OpenBSD on my Lenovo ThinkPad X250 as a daily driver from 6.7 through 7.1, but something broke in the X windows system during the upgrade to 7.1 and I couldn't be bothered to fix it, so that ThinkPad runs Manjaro Linux these days. The Spectre/Meltdown mitigations and disabled Bluetooth are fantastic from a security standpoint, but don't lend themselves well to convenient computing like running a Linux distro does.
