zfs-share vs. /etc/exports NFS export on Linux

I am setting up a share of a large ZFS storage via NFS on Linux. As far as I understood there are two possible ways to configure this: by means of /etc/exports or by using zfs-share. I have not been able to find any clear explanation about the difference between the two methods: are they just two different ways of doing the same thing or do they lead to substantial differences (e.g. available features, performance etc.)? Thanks.

ZFS on Linux uses the NFS subsystem under the hood; the benefit of doing it using ZFS commands is mainly that you can configure the share and the underlying storage from a single set of management tools.
