One all-enclosing partition or just use the entire device?

I received a 1TB hard drive that had a single 1TB partition. Because we do not need partitions on the drive (and I disliked using the path /dev/sdc1 instead of /dev/sdc), I went to fdisk, deleted the partition and created the filesystem on the…
