I'm playing Love and Deepspace, and I've played Jack Jeanne if that counts?
For Jack Jeanne, the 3D models aren't great, but I am impressed that the models are allowed to make contact with themselves and others (rather than hovering an inch off everything because the developers didn't want to risk clipping). It may be because all the clothes are rendered into the animation that they don't fear clipping? After playing Project Sekai, it was very impressive for me to see.
Not an otome, but the joseimuke Ensemble Stars also has 3D models in their dance performance, and they look sooooo good.
I've never heard of Toraware no Palm, so now I'm quite excited to try it out! Silent Whispers looks good, but I'm a bit disappointed in how their love interests look. When I watched the pv, all I could think about is which love interest looks like the lovechild of the Love and Deepspace love interests... Maybe when more information about the game and the character's personalities are revealed, it will be more interesting to me.
