Eeeh, that depends, really.Can agree on this one
Gerald had an amnesia, so player can shape his personality how he wants
On the other hand, Ciri is already well established characters and mature enough(21 in W3) to have more o less stable traits. So roleplaying with her is much more difficult and may feel unnatural
In Witcher 3 Geralt remembers everything - and there is still player choice in how he would act in certain situations.
Ciri is also way younger than Geralt, so it's not outlandish for her to change in personality in her late 20's or whenever the game will be set.
