Btrfs also works in nested lxd, so if that's your primary use I highly
recommend btrfs.
Of course, you could also keep using zfs-backed containers, but
manually assign a zvol-formatted-as-btrfs for first-level-container's
/var/lib/lxd.

zfs and btrfs are almost identical in that aspect (snapshot/clone, and
lz4 vs lzop in compression time and ratio). However, lz4 (used in zfs)
is MUCH faster at decompression compared to lzop (used in btrfs),
while lzop uses less memory.

That is, indeed, only available in btrfs
