I find PARTLABELs to be a lot more human-friendly than UUIDs.
The idea of UUIDs is that they are "unique",
so you can run two OS installs automatically without the disk IDs
colliding. We leave the collision probability of UUIDs as an exercise
for the reader.
I recall a couple of reports on this mailing list when data recovery was
necessary due to usage of UUIDs. Snapshots have the same filesystem
UUID, so some old version may be accidentally mounted during boot. Do
not use them in the case of LVM. Certainly FS labels are affected by the
same issue.
Do not take it wrong, in other cases I still recommend UUID as first
option to consider.
Specifically to partition UUIDs, sgdisk has an option for cloned drives:
-G, --randomize-guids
