zfs on raw vs gpt

Hi NetBSD users,

Any advice on using zfs on raw disks vs gpt partitions? I'm
going to use entire disks for zfs and don't need
root-on-zfs.  One advantage of using partitions seems to be
to protect against the risk of having to replace a disk by
a marginally smaller one.  But I'm wondering if there may
be a reliability penalty or other cons (also using raw
disks would be marginally less work).

Many thanks,
Pouya
