I have been using zfs for years from ubuntu 18. Easy snapshots, monitoring, choices for raid levels, and ability to very easily copy a dataset remotely with resume or incremental support is awesome. I mainly use it for kvm systems each with their own dataset. Coming from mdadm + lvm from my previous set up is night and day for doing snapshots and backups. I do not use zfs on root for ubuntu instead I do a raid1 software set up for the os and then a zfs set up on other disks - zfs on root was the only gotcha. For FreeBSD zfs on root works fine.
