IMO is near the top of mid tier. She has excellent pressure tools on shield and string large clumps of damage on many characters, but gets walled out insanely hard.
MU-wise:
Peach has about the same MU spread as or (both of which are mid tier) in terms of difficulty. She loses to characters like , , , , , all for the exact same reason, she gets walled out and cannot catch them. She loses to the majority of top and high tier (save 1 or 2 MUs like ) and either loses or goes even with borderline tier.
Character-wise:
Her ability to rack up damage is almost nullified by her inability to actually get in on a lot of characters and the fact that she is floaty causing her to die significantly earlier than others. She cannot kill worth crap. She has trouble approaching characters that have projectiles to control he aerial movement and although she can combo pretty well, also gets combo'd fairly easily. Juggling her is also a joke since she has poor horizontal mobility and a bad airdodge. Also, she doesn't have many options to force approaches and since she has a slow horizontal mobility suffers when she has to chase someone down.
Player-wise:
Now the only players doing anything notable are Kyon and Silly Kyle (and maybe Mikey every now and then). Silly Kyle places well in his region consistently (dropping a set or two here and there), but hasn't taken any big names and Mikey is busy with his life, so he doesn't attend much anymore (even when he did he didn't travel OoS). Her results are pretty much stagnant (especially seeing as Illmatic is no longer attending tournaments atm) and nothing notable his coming out of that character. If anything , , or should be higher on the tier list before .
This is just a brief reasoning of what I think, but in short there is definitely no reason to move her up on the tier list (especially if you think that results with a character shouldn't matter). Saying that she should be moved up when she doesn't have any results to prove she deserves her spot is just crazy and straight up theorycraft. Results DEFINITELY matte. I'm not saying she should be dropped to like low tier or something, but she is definitely a mid tier character at best.
