Mt. Komorebi is an awesome world. There is so much to do with it! Love having sims living there.
The upper map of Tartosa is like a blank slate. No shells so I can slap down my Batuu builds there. Also I appreciate having another warm world with access to beaches and swimming. That makes playing meersims more enjoyable. The lower map is like a sleepy little town. I have seen several of them during the summer when I was young.
I have room in my game for that sort of world. The opposite of San Myshuno. The pace is slow and the world is pretty.
That said I will be disappointed if all future worlds would be like that. I really like playing in the Expansion Pack worlds because they use have so much happening with them.
