PS3 Dollface's vehicle is technically Juggernaut, not Darkside.
PS3 Dollface was totally unlikeable as a character.
They gave her Grasshopper's name, Krista Sparks, instead of a new name, which was odd because she has zero in common with Calypso's daughter. They gave her the motivation of TM2 Spectre (fame), elements of the tragedy of TMB Dollface (having a mask stuck on her face), and a rotten, homicidal & insecure personality like Bloody Mary/TMB Spectre.
What is much better about TMB Dollface is that she is a consistent character. She is a victim. Her change of heart in her ending made sense because it's in her personality to self-victimize, so of course she decided not to free herself of the mask. TMB Dollface wasn't really concerned with revenge, even though she got it. She's both a broken and dangerous character, which is what made her an enjoyable video game character.
TMX Dollface however is not a victim yet the 2nd cutscene in her story spends minutes of time trying to get the audience to feel/sympathize for her situation. Instead of Dollface/Sparks committing to freeing herself in her 3rd act she comes up with a stupid wish instead, making the 2nd act of her story meaningless and making the character completely shallow. PS3 Dollface could be simply summed up as a self-centered serial killer model... you can check out a better version of the same exact character in the New Batman Adventures - I speak of Calendar Girl
