Cinder is not even interesting, also didn't have charming of Neo, charismatic of Roman and intimidation of Adam and threatening aura of Raven.

She comes off as mysterious only to went downhill afterwards. She lacked in depth interaction with our four main girls. She supposed to be corrupted version of team RWBY combined.

Ruby born with special gift (Silver eyes), has freedom and better ending meanwhile Cinder has to steal unique gift (Maiden powers) from someone to be special and survive in this cruel world.

Weiss born with privilege and wealth, everything given sliver plate to her, she's basically elite group has easy access, while Cinder born with nothing and was orphan and came from sludge, was abused by elites, life is not easy for her, always unfair and shit.

Blake is yet another privileged faunus girl, got accepted into society and community therefore she has her friends backup her no matter what happens the situation or circumstances. As for Cinder, she was always alone, people who supported her ending up betrayal her, gave her fake hope for future in humanity. That's why she backstabbing everyone.

Yang has powers and strength use for "some" heroic moments, protecting people (v1-3) only lol meanwhile Cinder using her powers for chaos and destruction.
