NetBSD-9 GPT on disks smaller than 2TB

[Sad Clouds <cryintothebluesky%gmail.com@localhost>]

Hi, assuming I'm using a system that doesn't require UEFI and disks are
smaller than 2TB in size. Is there any advantage of using GPT vs the
old disklabel scheme? Also if I want to use a partition (not whole
disk) for ZFS, are there any weird interaction/restrictions with GPT?

Thanks.
