Peach just feels and sounds more attractive, everything about her exudes beauty, so its very much hard for me to imagine her being less attractive than Med.
People can look very different from how you imagined them. Many of those visual theories would get shattered, guarantee you that
They tend to look about how I expected when it comes to their fashion, posture, and eyes anyway. Sometimes their avatar color theory or themes even matches up with other real life choices over how their relating to the image was why they picked it. Their character ends up pretty much matching up surprisingly closely with how they attempt to portray themselves here, except a lot more exaggerated when you can see them displaying it physically.
The voice is what always throws me for a loop, I never get the pitch right even if I get the inflection correct. Hairstyles and sometimes even hair color also throw me for a loop, you don't really get much detail from people's narratives about their hair unless it's noticeably unusual or they're that vain. There's a mild difference between how blonds and brunettes talk based on their priorities, so even people dying their hair in those directions tend to reflect similar themes based on intended presentation.
Only two people I've seen had me truly like "wtf" over it, the rest looked like symptoms of their narratives. The most surreal moments are when you can go like "So thaaat's what it looks like". I might have just been lucky, but people have a way of writing that yields how they're used to being treated before anyone's even responded to them, and that can even give away small things like if they act small or tall.
