Well where I work we have two major pain points with ZFS performance:

  when the filesystem gets > 90% full performance just drops

  scrubbing a large data set slows down access sufficiently that we can
    see the performance impact in our processing

Also why not just use /etc/esports I mean come on (with the newest
updates you have to use zfs commands to do the exports). 

However we have gone through a few disk failures and changeover was
quick and relatively easy to recover from.
