what? Teddie beats Chie/Yu free from what I have seen/read/heard. LK mention several times that mitsuru vs teddie is a hard fight in teddie's favor.
Chie has trouble getting in before she is in awakening. She can be zoned out.
My tier list would be
S: Teddie/Mitsuru/Aigis
A: Chie > Yu > Akhikiko/Yosuke
B: Naoto, Yukiko, Liz, Slab
B-: Kanji, Labrys
Chie has a new way to set up oki on Teddie involving JCing her sweep into 5C j.D. At this point in the game, Chie doesn't have any bad matchups. Narukami can't set up his vortex but his other tools are still useful. A month or so ago I had my friend ask LK who wins between Mitsuru and Teddie, LK said Mitsuru wins it.
Chie has no problems getting in with her speed, just requires good footsies. Even if someone like Mitsuru whiffs, Chie gets in and Mitsuru's slow start up leaves her vulnerable (and 5A being +1 is just too good). And Aigis is good but I wouldn't say top 3 because of having to use resources.
Lots of Japanese players put Chie and Yu as top 2 as well. The game has been changing lately. Naoto's SMP helps her, but I don't think it bumps her up far enough. The other characters have been gaining new possibilities, but Naoto stays pretty stagnant.
Your list feels closer to what the majority thought of the game last year, but Japan's been figuring things out.
