Neither because they're both horribly voice acted and just look bad.
Never liked the hello kitty necklace on Willow.
Willow had great voice acting and great quality, Vanessa sadly had poor voice acting and iirc her body wasn't that "realistic", which ruins immersion.
>Good voice acting
Im with Joshy on this. Vanessa's audio wasnt mastered well either, one minute you were at -16db and the next she's clipping, shame cause I like her voice actor. She did great in Coito Ergo Sum, which is fantastic if youve not played it. Anyway, Vanessa's quests were glitched as hell for me.
"Vanessa or Willow?"
Well obviously Yennefer.
Willow hands down. Vanessa's companion quests were just weird and the dialogue and the voice acting could improve a lot.
