I miss not being able to move disks from Apple to Linux and freebsd. That is, that's what I miss using APFS. No other aspect of APFS appeals to me over ZFS, except that Apple prefers it for time machine. That's why I use it.

If Apple supported ZFS as a first class in-kernel fs type, I'd be delighted.

I have already moved large zfs systems between FreeBSD and debian repeatedly. Snapshots are just ace! (by move I mean zfs export, move hard disks or re install OS and zfs import. zfs snap; zfs send | zfs recv is a different kind of "move" which I also do a lot)
