My opinion, almost all Sims worlds are lifeless and boring, across the entire franchise, even TS3's open worlds.
Take away the lots and the worlds are just empty shells with absolutely nothing to do other than 'move from here to there" and collect things in both TS3 and TS4, and of course in TS1 and 2 they were, literally, just backdrops for lots.
Mt. Komorebi was a real standout exception and City Living did a decent job of keeping it a little more interesting with the festivals and other activities that spawn, but most of the worlds don't have enough of this kind of thing.
