- An ulid is "sortable". But the whole point of an UUID is a random unique ID. Non guessable. Sortable is not a feature
you normally want from an uuid. And still UUIDs are still sortable. But it doesnt have any meaning.
- An ulid also encodes Time, an uuid doesn't.
- An uuid has less change of clashing: Its 128 bit vs 80 bit for ulid.
- An uuid is also url safe.
- An ulid is case insensitive. I don't see how this is an advantage.
