I second Mark about filesystem labels. Labels you can read and type.
UUIDs you can only copy and paste. Yes I did type them a few times,
but... With upside there certainly comes downside of filesystem labels:
if you are moving storage around you sometimes can hit the situation of
having two identical labels. Which during last couple of decades I was
able to get around.
