Look at Gura, that design is super simple, which helped it long-term. On the other end of the spectrum you have Fauna, who is pretty, but her default outfit had to be severely dumbed down for most merch and art. Like, you would never be able to make a 1:1 outfit match for a Fauna plushie, too much detail.
