I worked on a huge backend system that used ULIDs for everything. I liked them slightly better than UUIDs in general, but nobody coming in or using our system knew what ULIDs were, so we constantly had to explain what they were. If we used UUIDs there would have been far less confusion. In conclusion: Just use UUIDs.
