How unique is a GUID 12-bits is big enough and the generation algorithm is unique enough that if 1000000000 GUIDs per second were generated for 1 year the probability of a duplicate would be only 50 Or if every human on Earth generated 600000000 GUIDs there would only be a 50 probability of a duplicate.
While the UUIDs are not guaranteed to be unique the probability of a duplicate is extremely low See Random UUID probability of duplicates For your application it makes sense to use the UUID but you may want to deal with the extremely rare condition just in case.
