As a player who likes fantastical, Occult, and interesting things in my game, definitely Journey to Batuu.
It's different from most packs so it offers a new angle to gameplay, which is refreshing. It does have some restrictions, like not being able to use Occult powers and having to dress your Sims in Batuu CAS, but it's for the purpose of creating an immersive Star wars environment. The missions are pretty good, some of them can be a little challenging, which is nice, and the world is unique and interesting.
The objects are really cool, the droids and lightsabers are fun but function as toys when outside of Batuu. There's a fair share of fun items and decor that work really well for Geek Sims or children to have, and the build/buy really expands the creative options for building and decorating, especially if you like sci-fi, steampunk or apocalypse styles. There's a Sabacc gambling table that I like to use in shady bars and it's fun to play with.
The CAS is one of my favorite collections, it has a lot of masculine styles as well as feminine and some for kids and toddlers and the colors are muted and in various neutrals. Some can pass as "normal" while others are incredibly versatile for creating unusual Sims. I've used pieces for cultures, pirates, nuns, apocalyptic fashions, desert folk, eccentrics, steampunk, middle ages, paupers, fae folk, Aliens, Occults, etc. There's also a variety of face markings, head coverings and actual alien heads (Star Wars themed) that I've used to expand my Alien races and types. I also love the boot styles and use them all the time.
I don't own Dream Home Decorator so I can't say much about it except that it doesn't suit my personal preferences.
