should I put my multi-device btrfs filesystem on disk partitions or raw devices?

If I'm going to create a multi-device btrfs filesystem. The official recommendation from the documentation apppears to be to create it on raw devices; i.e. /dev/sdb, /dev/sdc, etc, but this is not explained.

Are there any advantages to creating a partition table on these devices first, either GPT or MBR, and then creating the filesystem on /dev/sdb1, /dev/sdc1 et cetera? Does feeding btrfs whole devices have some particular advantage, or are these basically equivalent?
