I find V2 is better for doing her dark / horror moments with the glowing or shadowed eyes.
V1 fits multiple styles better.
Highly recommend using Img2Img.
I tend to schizoprompt so YMMV.
V1 fits multiple styles and Img2Img better.
V2 might've gotten overfitted so is better for the horror / dark moments with her glowing / shadowed eyes, or for PNG renders.
