Since the original post is about OpenBSD and the parent is about FreeBSD, just some addition:

1. ZFS is not supported in OpenBSD. Here's why OpenBSD doesn't have ZFS (pretty much every other BSD does): https://old.reddit.com/r/openbsd/comments/7xsx8u/why_doesnt_... (There's probably a better link out there)

2. Jails are not supported in OpenBSD. AFAIK, they are a FreeBSD-only feature.

I'm caught in a strange situation where my MacBook Pro wireless is supported by OpenBSD (and not FreeBSD) but I really like ZFS and Jails. Some features like those about trackpads, sound, wireless "just work" in a basic Arch install but not on FreeBSD. So I'd take "FreeBSD does everything that Linux used to do for me" with a grain of salt, because that has not been true for me.

OpenBSD does have pledge, on the other hand. And yeah, different systems have different features and tradeoffs; some people could legitimately say to take "Linux does everything that FreeBSD used to do for me" with a grain of salt, because that has not been true for them (say, if they like ZFS + boot environments, which is a relative pain on Arch).

I still haven't gotten boot from encrypted root pool with GRUB set up properly; it fails and drops to initramfs, I manually import and mount, after which it continues boots fine ¯\_(ツ)_/¯
