Depends on your needs. For me it was essential to have the same name of the disk no matter to what server I connect it. Label is working fine for me. Anyway I'm glad that you resolved your problem.

Maciej I didn't know if the label would work in loader.conf. This solution suggested by Adam worked and seems much simpler than labeling the filesystem. hint.da.0.at="scbus6" Thanks.

Re: fixating USB Storage
Thanks, I got the part where you can label the partitions but the loader doesn't look at labels. Loader looks at ufs:/dev/da0 So how can this be resolved at "boot" time (not mount time). Thanks.

The real issue is that the USB boot device sits at da16 and if any of the da members below da16 drops, the usb boot device becomes da15 at next boot.

Sounds similar to my experience. Normally my internal 4 slot memory card reader is assigned devices da[0-3] and when the USB memory stick is inserted it comes up as da4. If the USB stick is present on booting then it appears as da0 and the card reader is da[1-4].

I was having an ongoing issue where this external USB drive's device number assignment would change from one boot to the next, toggling back and forth between da0 and da4 (strange!). Then just the other night, something led me to one of Warren Block's web pages describing how to easily label a volume and use that instead in /etc/fstab, so shifting device assignments no longer matter.
