I posted my thoughts on another thread; I'll keep it as short as possible here.
It's very disheartening, seeing the majority of the Internet going "I wish so-and-so was uchi so I'd like the personality! Quinn = ugly, like the rest of the uchis! Eww why is Sasha a BOY?! but
eyelashes!"
I'm very glad Quinn fits the mold of the rest of the uchis; the designers have made it clear that they are not intended to be cute uwu girls, and it's very befitting of their personalities. Uchis don't subscribe to the norms of conventional attractiveness, which means they get the short stick in terms of fans liking them.
Just like in real life, unfortunately.

I personally really appreciate that the designers stuck to their guns; uchis are my favourite personality specifically because of this.
(I don't know, maybe I'm just old and out of touch and uchis are only good if they're cute uwu. I don't know...)
I'm so glad that Sasha isn't another peppy rabbit; he's going to do great as a fashionista gender barrier breaking lazy boy, and I'm rooting for him from the sidelines!

(though he's still not on the shortlist for my island because he'd share Hopkins' script. Though, seeing the negative fallout from him not being female is starting to sway me...)
