UUIDs are easier because they immediately scan as random values when you look at them. They are a clear indicator of surrogacy in a way that a spread-out sequence is not.
It doesn't matter how difficult picking a sequence is (and your post is odd because I don't think I gave any indication of unfamiliarity with Postgres?). It's a cognitive concern with keys that look simple but are not obviously unrelated (as a normal sequence is by convention or UUIDs are by definition) to the rest of the table.
