I'm not actually as bitter about it as I sound, but I do find it mildly irksome that this is such a nicely done figure-- the pose, the sculpting, the face, the painting, all pitch-perfect –and yet Kagami gets a super-expensive shaft-job, out of Good Smile Company even! Sigh. I couldn't find a complaint with this Yoshika Miyafuji figure if I tried. The hands are elegant. The gun and mech legs are detailed but not overdone. The eyes are lively. Siiiiigh!
At ¥7800 (about $81 USD), Alter's figure will be not affordable but not end-your-life expensive either. She's due out this September.
This figure is extremely well done as well, although, I think what helps put it apart is just how unique a design and how much more deep the details are of the character to compare to.
The other Kagami figure has an odd facial expression-- one that isn't matched by the way the face is shaped, when someone closes one eye they lift their cheek slightly at a minimum. Go ahead, try winking an eye or just closing one eye and not feeling your cheek lift at all. But the other figure doesn't show that at all, it literally could be the same face with both eyes open. I think the hands are too chunky (by contrast, the figure I linked above has "cartoony" fingers that don't look pudgy), which I think is another thing that's bothering me.
