One downside of Linux is that most distributions ship terrible, hacked together amateur code and ill-thought out monstrosities like systemd, pulseaudio and so forth. This is getting markedly worse over time and infecting more and more distributions.
By comparison, FreeBSD is clean and OpenBSD is immaculate. Neither one has the sexy latest features, but for servers, that’s a strong plus. And, programs are frequently faster and have less jitter on the BSDs, owing to better networking stacks, better drivers, and better schedulers.
