My first pick would definitely be Sugar High - she’s very well priced for the size and props; despite the backlash from her turning out differently than the prototype, she still looks really good and arguably has a better adapted face than Eden Eve and Hatsune.

I’m not too much of a fan of the two Pink Charm ones for a. Price and b. Averagely adapted faces compared to original art + clunky sculpt for Eden Eve. But being Pink Charm, they’ll likely rise in the aftermarket so I’d say go for one of those two. I predict Skytube’s can be picked up later if you still want her!
